Two part introduction and
construction of this reflexed Super in Feb. 28 & March 7, 1925 RWI
issues. Layout in March 7. Used Acme 600 meter RF transformers (Type R2 or
R3) for IF; very unusual! Used 6 tubes and a Brownlie Crystal Detector
(6+1). Original set used 199s, but Benson says 201As will work. Used Plate
Modulation of Ultradyne fame.
Benson said reflexing was easier with the higher intermediate
frequency, possibly 500 KC
[??]. That's close to the standard 455 KC today. Benson is called "Noted
Radio Engineer" in article.

In
the Philadelphia Evening Public Ledger, "The Radio" section, November 22,
1924, is the fourth in a series started October 25, 1924 and ending
November 29 with the construction of the IF transformers. Captain H. J.
Adams was the Army's Chief Communications Instructor Twenty-eighth
Division, United States Signal Corps. For the times, different layout
design using subpanel.
Oscillator coil has three wound sections. Very small Pickup coil next to
tube one's socket. Adams IF
transformers are round (Tuna Can) except one-quarter flatten on the side
to allow it to stand straight up. A small loop antenna can be used with
the Captain Adams. 10(?)x 30 inch panel. |

by Clinton Osborne. RR, May '25, list numerous brands of IFs for use in
this radio. They must all be near 45 K.C.: All-American, Baldwin Pacific,
Branston, Jefferson, Phenix, Receptrad, Remler, and Silver-Marshall. The All American Oscillator
Coupler was NOT used here, likely a Remerl 631. RR, Oct '25: Construction of
untuned & tuned 45 KC IFs shown. Same construction info, woodcut

on December 30, 1918. Applied for U.S. patent in February of 1919 (issued
in June 8, 1920, #1,342,885). His U.S. patent was overturned by the U.S.
District Court of Appeals of the District of Columbia in December of 1928.
A Frenchman, Lucian Levy, was judged to have disclosed basic principals of
the circuit in 1917. So why do so many consider Armstrong to be the
inventor of the superheterodyne? Walter Shottky may have stated it best in
1926: "The "word" seems, at any rate, to have been far less important than
the "deed," and there appears to be no doubt that it is Mr. Armstrong and
his collaborators to whom we owe the deed, which has made the
super-heterodyne method such an invaluable instrumentality in radio
engineering." (Must reading is "Who Invented the Superheterodyne?" by Alan
S. Douglas, The Legacies of Edwin Howard Armstrong, published by The Radio
Club of America, 1990.). |

(likely the 6 tube set) from France went to the Signal Corps Museum at
Fort Monmouth, the "honeymoon" suitcase portable second harmonic superhet
went to the Ford Museum and prototypes of the RCA six tube second harmonic
superhet went to the Smithsonian and AWA. |

(Note 23) Besides
actually building all of the pre-production models, Harry Houck's main
contribution, to what would become the first RCA production superhet,
would be his second harmonic invention. There were several inherent
advantages to this scheme - reduction of one tube by combining the
functions of oscillator and first detector; elimination of antenna
radiation, and; reduced interaction between antenna and oscillator
controls. Houck saved an additional tube by reflexing the first IF
amplifier back through the RF amplifier. Drawing from Houck's second
harmonic patent filed March 3,1923, #1,686,005, issued on October 2,
1928. Harry Houck would
eventually receive at least $100,000.00 from Armstrong for his work on the
superheterodyne. Just a few days before filing for his second harmonic
patent, Houck assigned rights to Armstrong. |

19, 1924. Ad says, "Rolls Royce of Radio". Sold as manufactured set in May
1924 (X) for $150 in "beautiful piano finish solid mahogany cabinet and
unconditionally guaranteed for one year" and complete parts for $75. Then
in June 1924 (X) they advertised only the complete kit/parts. Leutz/RCA
law suit had an effect. Ads for just a couple of months. Regeneration
here. Tuned plate circuit on first stage for better amplification. Was it a re-packaged (something of
someone else) set? |

[From
Dale davenport:] Truth
is, I've never been sure about the AK "Super." I've had it for years
[2003] and it's currently in the attic of my shop, somewhere. It's stood on one
end on a dirt floor and is in pretty sad shape. It's exactly like a model
20 ,but it's about three feet long. The front panel is like a model 20 in
that the holes, knobs etc. that are model 20 ( or 10 ) and it has only two
dials, set to the left side.
he front panel is metal,
same guage as a 20,
has the spot welded little rail / shelf along it's length at the
back, supporting the various pieces, all of which appear to be AK model 20
( or 10 ). From memory, it
has two large tuning dials to the left with a standard AK tap switch set
between them at the bottom,
a AK lozenge nameplate top center, two of the AK model 20 rheostat
islands set to the right (mirror image to the tuning knobs to the left). I
don't remember if it has two on / off switches or not but seem to remember
that it does and one is "A" and the other "B" source. The little support
rail looks like AK too but "I thought" it looked a little "cobbier" than a
usual stamped one and that would make sense for a "one of" model I guess. Yes, it does have
the milled corner "trim" buttons. Paint is too far gone to tell but seems
to have been the standard AK "Crystalline" finish rather than wrinkle.
Circuitry is made up of various AK 20 Bakelite tube islands, single,
triple, etc. The tuning condensers are metal frame like those in a model
10 rather than the bakelite model 20 type. The AFs and IFs are what
appear to be normal model 20 "can" types mounted in the usual way on the
bakelite. Whole thing is eight tube (if I remember correctly.) Wiring and coils antenna coil are
pretty much standard looking for a model 20. One coil seems to be a usual
tapped antenna model and the other wound to be a coupler with a little AK
knob (like on the tap switch). Where did it come from? Beats me, I got it in a trade years ago with
a fellow in PA (interesting hunh?).
He had picked it up at a local auction as I recall and thought it
was a home brew. Prototype??

Layout |
|
All parts are staggered - unusual. The author says this layout
must be religiously adhered to or there will be no results. Two IF
transformers and one audio. The IFs shown are unknown and article doesn't
tell. They are black blocks with a label that has a circle-like logo.
(There were three known companies that made black square IFs:
Hayne-Griffin, Sangamo, and Abbott.) The output coil is home-wound on a
bobber of 2 inch diameter with a 1 inch core. Pictured with enclosed Acme
tuning capacitors.
Interesting layout for a 6 tube design. Used 199s. Used a
flashlight battery soldered in for grid bias. Claims it can be made for
$55. Baseboard 10 inches
deep. 7x18 inch panel. |

Can be configured as a
Four-dial Super. The detector
Stage is the single tube heterodyne stage making it a Superhet, much like
the Oscillator/Mixer stages from years later. With the use of untuned RF
transformers such as "Acme, Ralsa, Erla, and others", the two additional
17 plate condensers can be eliminated with degradation of performance in
selectivity and volume. This would give the appearance of a two-dial
Super. This is a single oscillator/mixer stage with feedback and the
addition of two RF stages and two AF stages. The first two RF stages
utilized "any Neutrodyne coil" for the amplification factor of 8 to 1 per
stage. Any iron core audio transformers were used if they were 5 to 1
ratio for the best results. Used a flashlight cell for 4.5 volt bias. Used
a 50-turn honeycomb coil and variable condenser (size not giving in this
construction article) for the feedback loop. "It goes without saying that
all the tubes, detector tube (3) included, must be hard amplifying tubes,
such as UV201A, C301A, and UV199 or C299. A soft tube like the UV200 will
not work at the high plate voltages." |

Note
round label on top of round case. I believe the case is shielded as there
is a reference to a shielded case in the article for the "Baldwin Pacific
- Best" radio. The #5 transformer is the IF [three required] and the #10
is the Filter transformer [one required]. Black nickel trim finish. "…hook-up print packed with each
transformer." Radio, May
& June 1924, ads says "A complete knock-down SUPER SET ready soon."
[Knockdowns were illegal by RCA injunction.] Manufacturer associated with
"Radio" magazine (Pacific Publications) in San Francisco. Is Baldwin the
same as Nathanial Baldwin? Very possible. It's also possible Gerald M.
Best created this for Baldwin-Pacific Company just before he went to
Remler. In 1926, it's reported he endorsed the circuit. See Remler.

"All Wave". Used UV199s.Completely brass shielded. Could have General
Radio 271, Jefferson 150, Silver Marshall 60 KC, Baldwin-Pacific Shielded
IFs. Remler NOT mentioned! I believe the case is shielded as there is a reference to a
shielded case in the article for the "Baldwin Pacific - Best" radio. But,
Best mentioned in the article that the IF should be between 40 and 50 KC,
which, at 45 KC, would be perfect for the Remler IFs. Maybe didn't want to
create conflict of interest. Sub-panel is 16 gauge brass and is 7x16.
Brass shields were used to sepaarate various sections of the radio inside
the case. Adapted to a long
wire outdoor antenna. A hand-wound "loading coil" was used to compensate
for various lengths of antenna wire starting at 75 feet. |

Another kit reference
in PR, Feb '26, P187:
Referenced in "What’s New...Apparatus Approved by Popular Radio". Likely this radio is the
same as Allen Jochum's. From Allen Jochem of Quincy, IL, email 2/02: "It is a chassis only. Used 8 uv199's about the size of the
Apex Microdyne. [X] The set does not have a name on it, but is otherwise
engraved." Note the different shape at the bottom and rounded top of these
transformer cans now of all metal construction. In the middle of the set
are two large spiderweb coils, maybe for the oscillator circuit. Engraved, but no name 7x18 inch

Branston brochure
(undated) says it is a Reflexed Super. "...reduced the number of tubes to
seven UV199's or UV201A and to diminish the size of the required panel to
7" X 21 inches". "Works like ten."
The kit offered is: 3 IF matched transformers in one unit [R-200],
one IF tuned transformer [R-201] for first or last stage next to the IF
unit, one Shortwave unit [R-202], one Special Tuned RF Coupler unit, I
believe, for reflexing [R-203], one double unit Audio Transformers
[R-204]. There is a stand
alone single IF transformer [R-205], also. The IFs are of laminated silicone
steel. The cases are designed to keep the leads short. These are the same
basic shaped IF transformers as used in the Como Super-Het, but have
different side connectors! (Comos are actually General
Radio 271 IFs.) Good ad in RB Nov '24, P16 &
RN Nov '24. Sears catalogue shows the kit at $29.95 in 1925. Set shown in
PR, March '25, P118 (partially assembled & called the "Accessory Kit")
and also in American Radio catalogue April 1925. RN for Dec '24 (P1101)
lists "Kit". RB Dec '24, P323 shows good parts layout. RB - Jan '24 - P592

Flewelling Uniformers
were designed of polished hard rubber with terminals protruding from the
top. The Uniformer block has recessed areas on the top so the Flewelling
tube socket can be attached to two terminals on one block and the other
two terminals on another to build a compact arrangement of IFs and
sockets. Ad says a six-tube
set can be as small as 19 inches and 3 1/2 inches deep. Located on 2975-77
Cottage Grove Avenue, Chicago. |

The Daven Super Amplifier
is an entire bakelite unit with three tube sockets and associated
resistances used as the IF stages of a Superhet. The Type 3-K was a kit
without tube sockets. Both
used Daven Type MU-20 tubes. RN - March 1926 - P1373. See Popular Mechanics magazine

Custom-built by Charles
A. Dean of Binghamton, New York, likely for his personal use and not to
resell. This set has what
appears to be an long wire antenna coupler behind the front panel near the
center. This might explain the knife switch at the far left interior and
the front panel markings that say, "Loop or Variocoupler Secondary" with
arrows pointing to external binding posts at the top and bottom of the
front panel. The Barry-Receptrad has this same arrangement with binding
posts. The Dean appears also to have a jack between the the two binding
post for a connection to a two-wire loop antenna. The standard volt meter and the
milliamp meter were not included on this Receptrad. The three headphone
jacks are above the filament controls like on the Barry-Receptrad, which
seems standard. Front panel
is three inches shorter than the standard early Receptrad at 39.5 inches.

This company at 22 Warren
in NYC built self-supporting coils for various circuits, like Roberts, DX
Superdyne, Browning-Drake, and typical TRFs. The Model "FC" was designed
for specific use in the O'Connor "Frequency Changer" that, when set up
with a five tube TRF or Neutrodyne, turns the radio into a
superheterodyne. Other radios can be used, also. Model "FC" retailed at
$6.00. See Radio Broadcast June & August 1925 for "Frequency-Changer"
articles by A. O'Connor! See
"O' Connor" below. |

"Takes the 'IF' out of
putting the set together" (PUNNY)
Eight tube module [18 lbs] & a six tube unit [New 11/27]. The
pre-assembled module was a wooden structure that covered the guts of the
radio, leaving only the tubes and their sockets shown. Used DeJur parts as
recommended. "The Gradergood Co., 1435 Welton St., Denver" is sales
representative with a store, "Radio Stores Inc" next door at 1433 Welton.
Ads said the company guaranteed if the unit "went sour" they'd replace
[seemingly forever] if the unit hadn't taken apart or abused. RN, Jan '27, P788, article &
scheme [no internal values give]. A complete 8 tube schematic is shown on
page 84 of the Nov 1927 S.
Hammer Radio Co. offered completely wired version in Corbett cabinet for
$156 in Sept '27. CRCB, Sept. '27, P172 & 173, two page ad. American Radio, Sept '27, offered
the unit for $63.00 [retail $105.00] and the complete kit without cabinet,
batteries, and tubes for $75.84 [retail $ 126.00] . |

Add two or three stages of power audio to this Unit to make it a complete
8-9 tube superhet. The pre-assembled module was a wooden structure that
covered the guts of the radio, leaving only the tubes and their sockets
showing. A complete 8 tube schematic is shown on page 84 of the Nov 1927

Blue prints offered to
the public April '23. Radio News, July 1923, first "C" ad. The "C" was in
the marketplace nearly a year before RCA introduced their Super-Het. Note 20: "...uses eight tubes.
Depending upon the sockets and filament rheostats, the tubes can be Type
UV199 or Type UV201. It is designed for loop antenna, but an external
adapter unit was available for outside antennas. The Model J 2-stage RF
amplifier was also available. References: Antenna Adapter "K" and the
2-stage regenerative RF amp "J".
The Model C has 4 rheostats and one 'stabilizer' potentiometer. The
audio stages are biased with a 4 1/2 v. C battery inside the cabinet."
Early IF transformers were General Electric (RCA) Model 1716s until RCA stopped shipments to EIS in March
1924. Acme Open Frame & General Radio IFs were used until EIS Model C
"Radio Frequency" transformers were available. These Model "C" IFs are
broadly tuned to peak at 47 KC [6389 meters], whereas, previous maker IFs
were 30 KC (10,000 meters). EIS Model C IF transformer has "3 meter
selectivity at 300 meters" (1000 KC) according to RN, June '24
ad.
Also sold through Norden, Hauck & Co., Philadelphia, which
advertised RN, Aug '24, P252: "Wired" / Complete / Kit / Parts. |

RN info in Jan '27, P842,
says Norden Hauck provided all the data for the schematic. Says RCA UV1716
IFs would be a good substitute for EIS coils. Early versions did not have
removable fixtures for the antenna inductances & oscillator couplers.
Most didn't have engraving on front panel that said "Superheterodyne"
& may have been only those shipped early. 1st tube is Oscillator, 2nd
is 1st detector, 3rd is RF amp, 4th is second RF amp, 5th is 2nd detector,
6th is first audio, & 7th is last audio. All UV201A tubes. "New Model
C-7". "The Rolls-Royce of Reception". Note
20:
"...uses 7 tubes & no loop. Inputs are provided for long &
short antennas. One less IF stage than Model C. Has only 2 rheostats, one
marked 'Master' & one for the 2nd IF marked 'Volume'. No 'Stabilizer'
control. Uses 2 C batteries - 9 v. for the 1st detector & 4.5 volts
for audio - also located inside cabinet." "...used 2 tuning caps by
General Radio & the osc cap was marked 'Heterodyne' & antenna
tuner was marked 'Wave Length'...Sockets by General Radio, audios were
General Radio Type 231A or GE Model UV712 & meters were Jewell or
Weston. Western Electric made bypass caps & filament switch." Three
jacks - one for each audio stage. Two different styles of IF train (see
pix). IFs are broadly tuned to peak at 47 KC [6389 meters]. EIS Model C IF transformer has "3
meter selectivity at 300 meters" (1000 KC) according to RN, June '24 ad.
Assume C-7 is same. Model C-7
is a First Harmonic. "...Experimenter's Information Service C-7
design...". No untuned, no tuned, 2 IFs, 2 Audio ^. "Improved
Regenerative". RB - Dec '24

Three-Dials. John Wolkonowicz told me of this one. Model not verified but
likely. It's a model C-7 inside and a Model C-10 outside. See these notes:
Panel is 40". Leutz says the C-10 is, "…a C-7 Model...with (three) stages
of TRF…". Note 20: "Model C-10 is similar to the C-7, but has three tuned
RF stages ahead of the first detector for a total of 10 tubes and five
tuning capacitors. The RF tuning is ganged so there are only three tuning
dials. This model was designed for the Navy with plug-in coils covering
50-600 meters." IFs are
broadly tuned to peak at 47 KC [6389 meters]. EIS Model C IF transformer has "3
meter selectivity at 300 meters" (1000 KC) according to RN, June '24
ad. Assume C-7 is same. |

Three-dials. "…this new design by Charles R. Leutz...". RB June 1925 P298 ad by
Norden-Hauck. First 3 stages are TRF, a regen detector, then, Osc., 2
stages of IF, 2nd detector, and 2 stages of AF. Leutz says, "…a C-7
Model...with stages of TRF…". Note 20: "Model C-10 is similar to the C-7,
but has three tuned RF stages ahead of the first detector for a total of
10 tubes and five tuning capacitors. The RF tuning is ganged so there are
only three tuning dials. This model was designed for the Navy with plug-in
coils covering 50-600 meters."
Scheme also in RN, Dec '25, P821. IF frequency is 6389 meters [47

Flewelling was "the
inventor of the Flewelling Superregeneration Circuit of the early
broadcasting days". [Wonder what Armstrong had to say about that!] Used an
interesting "capacity strip" to hook most wires to under the sub-panel.
Leaves only about six inches of external wiring. The sub-panel, supplied
by Flewelling in the kit, is already drilled with tube sockets already
mounted on it. It's drilled for all transformer terminals. Flewelling name
is the top of each IF transformer and "these trade marks should all read
right side up from the front panel." If not, the transformer must be
reversed. Used four Flewelling Long Wave transformers, one Flewelling
T.R.F. transformer, and two Flewelling audio transformers. Used the center
lead and one outside lead of a tapped loop. |

This is a three-dial
set! "A filter circuit is
nothing more than a stage of tuned RF designed for a long wave length and
permanently tuned for that wave length….It occurred to the writer
(Fournier) that the intermediate stages of a super-heterodyne might just
as well be designed as tuned RF amplifiers operating in the neighborhood
of 5000 meters." Used 201As or 199s. 7x30 inch panel. |

This was the Silver
Marshall Laboratory Model. It had aluminum blocks shown RB June '25. Kit (shown in PR June '25)
includes 2 "Two-Ten"s (IFs) which peak at 5000 meters (same IFs used in
the 401 Unit), 1 "Two-Eleven" (Filter), and 1 "101B"(Coupling Unit) with
instructions. Used 199s. Had 1.5 volt flashlight battery for tube bias
while SM used a 4.5 volt bias battery. See Silver Marshall. General Radio
Repair, 36 West Randolph, Chicago. Picture of the set in the ad is
inverted possibly to hide the fact it's a SM radio. Panel appears to be 7x28, rather

"All Wave". Used UV199s.Completely brass shielded. Could have General
Radio 271, Jefferson 150, Silver Marshall 60 KC, Baldwin-Pacific Shielded
IFs. Remler NOT mentioned! But, Best mentioned in the article that the IF
should be between 40 and 50 KC, which, at 45 KC, would be perfect for the
Remler IFs. Maybe didn't want to create conflict of interest. Sub-panel is
16 gauge brass and is 7x16. Brass shields were used to sepaarate various
sections of the radio inside the case. Adapted to a long wire outdoor
antenna. A hand-wound "loading coil" was used to compensate for various
lengths of antenna wire starting at 75 feet. |

Three-dial set! Switches
from 4-tube Regenerator to 9-tube Super Het. "One stage of TRF with
regeneration, a non-regenerative first detector, three stages of iron core
medium frequency amplification--from 30 KC to 60 KC--a non-regenerative
second detector, and two stages of transformer coupled audio
frequency." Three-part weekly
series in RWI beginning Feb. 6, '26 (13 & 20). Although brand of parts is not
specified in April '26 RN, developer used Silver-Marshall Oscillation Coil
and IFs. April '26 RN shows scheme & much more info. Ad in RWI March
6, '26, P2, and RN June '26 show General Radio IFs. Also see Note 21.
Schematic also in Secor's "Super Het - Which One?" - Radio Listener Guide
(No Month 1927). Quoted from Secor article (Publication unknown): "One of
the latest superheterodynes which comprises simply a few improvements in
the general circuit arrangement, coupled with one stage of tuned radio
frequency ahead of the first detector, and shielding, to increase the
range of reception, is known as the Fenway. On studying this circuit you
will see that you can utilize the features of this super?het if you
already own one, by simply adding one stage of tuned radio frequency ahead
of the first detector. Mr. Fenway in his superhet shields various parts of
the circuit, and those interested in these desirable features should
peruse carefully the articles which have appeared in various radio
journals. Referring to Fig. 3, the diagram of the Fenway superheterodyne,
you will note the antenna coupler. This may be any standard coupler with
or without a rotor which is not used, the proper size of variable
condenser being used to tune the secondary of course. Next for our
consideration comes the radio frequency coupler labeled L1 and L2. As
diagram Fig. 4 shows, this coupler “B” may be an ordinary variocoupler,
using the secondary or tickler as the rotor P, the secondary of the
coupler being tuned by a suitable size variable condenser, V. The
oscillator coupler with the three coils, L3, L4, and L?5, may be of any
standard form, or else constructed according to Mr. Fenway's
specifications, as given in articles referred to. The intermediate
transformers may be of any well-known make, Mr. Fenway specifying those of
the iron core type. (Likely S-M - Editor) This super-heterodyne requires
three tuning controls or variable condensers, and it is the writer's
opinion that the same results can be obtained with a nine tube lineup,
utilizing an extra stage of intermediate radio frequency (4 stages in
all), as pointed out previously."Fenway, 29 West 64th Street, NY. Moved in
Dec '28 to 831 Eighth Ave (across from Madison Sq Garden)...then known as
DX, Inc. Entire radio is
shielded as around inside of the case, top to bottom, and individual tubes
stage copper shielding. (I
bought this radio in August 2007 for $1750 including shipping from a
collector in New Jersey. He had it for some 15 years and knew the original
builder! Entire set of parts might have been bought from "Chas W. Down"
radio shop in New York. See ad.) |

first advertised in PR Dec 1923 (X).
McMurdo Silver was Haynes' assistant who helped build 20 Hets (some
shown in article including a three-dial version) in the Fall of 1923
before this set was described as the best. It used square black case IFs.
It's based on the multi-cabinet set immediately above. Construction
article in Jan '24, RB. This Super was first tested at WHAS, Radio
Broadcast Labs, Louisville after 19 previous models! McMurdo Silver went
on to be Hayne's store manager when the Chicago location was opened. Panel
is 7x24 inches. |

This radio is virtually
identical to the Lincoln Model 8-80 One Spot. Differences are the Antenna Coil
lies horzontally on the Hollister and the two front panel poteniometers
were set further apart on the Hollister. This radio used a standard
hardwood cabinet and a "Finely Grained Walnut Bakelite (front) Panel",
unlike the two tone metal cabinet & metal panel of the Lincoln
8-80. Only one connection on
Antenna Coil rather than the two (long & short) on the Lincoln 8-80.
Four screen tubes (UX222) and four "Manually Tuned", "Lincoln 101" I.F.
stages. Also Used 3 - 201A and 1 - 171A. No untuned, no tuned, 3 IFs, 2
Audio ^. Used Lincoln 1 "102" Osc. Coil, 1 "103" Antenna Coupler, 4 "101"
Tuned IF transformers, 1 "105" first AF transformer, 1 "106" second AF
transformer, and 2 "104(L & R)" condensers. Kit: $92.65 ^. Radio for July '29 has article
& scheme on Hollister. Barawik Cat., Sp & Summer '29 says "Gain
for first stage (audio) is 4.4, for second stage is 3.7. Range from 40
cycles to 5,000." Used the
Clough audio system as touted in CRCB of Nov. 1928. Covers 50 cycles to
7,000. Can use 15 foot indoor aerial, but ad says it can be used without
any antenna at all!
William H. Hollister (designer) wrote the book, "The Secret of the
Super". Address: 329 South
Wood Street, Chicago. Lincoln Radio Corporation also sold Silver-Marshall,
Tyrman, Scott, and HFL superhets out of this address. Lincoln also made
available a Hollister power supply; "AB 250" for $60 retail (see CRCB for
March 1929 ad), which used a 381 tube. |

the upper left of the front panel to help one of the major tuning dials
control the oscillator [I think].
The oscillator coil is fixed approximately 3.5 inches across.
Modified to 9 tubes with push-pull using Thordarson transformers. Says "Mfg by Wm. Holtzmark, St.

the transformer and two model numbers "3258" and "3259" (Alter's stock
numbers) with the same info as follows: "The effective band width is
13,000 cytcles wide. To be used with C299 or CX299 (dry cell tubes)
only" "Long Wave 10,000 M,
Input (30 K. C.) Each $1.98."
(Reference to two RF transformers as early as Feb '24 - PR) Ad says: "Best specifies Jefferson
IFs for his new Superheterodyne." Listed as parts for Midget Super in RR,
Oct '25, P12 (See Radio Review below). Includes "Tuned" and "Untuned" IF transformers. See Best above. Also see Radio
Owners Service Company below.

Three-dial Super. The center dial on the front panel is connected to the
variometer which varies the inductance of the antenna tuner. See Note 21.
"All Wave". Used UV199s.Completely brass shielded. Could have General
Radio 271, Jefferson 150, Silver Marshall 60 KC, and Baldwin-Pacific as
Best says these are all shielded IFs. Remler NOT
mentioned likely because I don't think they are shielded
units.. Sub-panel is 16 gauge brass and is 7x16.
Brass shields were used to sepaarate various sections of the radio inside
the case. Adapted to a long
wire outdoor antenna. A hand-wound "loading coil" was used to compensate
for various lengths of antenna wire starting at 75 feet. |

A good way to help
distinguish this kit from most is to see if it has one of these three
General Radio Oscillation Coils:
# 277A, 277B, & 277C. Parts list recommended three small
Benjamin tube sockets and five large Benjamin sockets. Recommended one
Weston voltmeter. Used three Jefferson IFs. Could have Thordarson, All
American, Lyric, or Karas audio transformers. Complete kit at $82.75 or
$89.50 (special audios) sans cabinet and matched tubes at $2.50 each. RSOC is addressed at 660 12th

Radio Retailing for August '25, Kardon was sued after he sold only ONE

[Use ad from RN - July 1929 - Ad from estate of REL - Alice
Lacault and the one on Page 1130 in RN, June 1929.] Complete construction info is
shown in RN, July 1929. This is Lacault's last design; the first time his
famous Ultradyne Modulation system used in conjunction with screen grid
tubes. Introduced in RWI, Ap 6, 13, & 20, '29. RN text says he
"labored to complete this, his finest design, explaining how weak he was
in his last days". (He died March 12, 1929.) This set without the
associated Push-Pull audio amplifier and the power supply unit looks like
a simple six-tube TRF set with two single variable condensers. The P-P amp
is AC driven, but the radio itself is battery operated!! Used 3 - 222s and 3 - 201As. Used
1 SG tube in Modulator and 2 SG tubes with 4 tuned circuits making a
bandpass filter for IFs. There are only two stages of IF, as such. The
distinctive "tuna can" Ultraformers are NOT found here. Rather, these are
simple coils of wire on standard bakelite tubes. You'll find four of these
coils here. Lacault considered 120 KC as a "high IF". There are three
large metal shield boxes found inside this set; the oscillator stage and
the two IF stages. One of the coils is found in each of these boxes. The
fourth coil is outside the boxes. Three tubes inside the three boxes with
three outside. RWI, Ap 20,
'29, Cover & P12-13: Lacault RE29 Power Supply. Other RWI articles in
early Ap '29 issues and Ap 27, '29 issue. See Madison, Phenix,

Lacault article from RN Dec. 1923. First reference to Lacault. It's a 10
tube super and built in three units, tuner-oscillator and first detector,
IF amps, and the last detector with AF amps. The three units stack on top of
each other into a single enclosure. Oscillator coupling accomplished with
with honeycomb or homebuilt coils. IFs could be either homebuilt coils or
RCA 1716 transformers. See

Three-dial super. Gorgeous set! This appears to be factory assembled as
the workmanship is superior. Information from Art H. Redman from Portland
(8/05): "I would of got back
to you sooner but first I had to make a trip to the Mulnomah County
Library to find some information. In 1923 Thomas J. Langhorne worked for
the C.L. Boss Auto Company. The City Directories from 1924 to 1926 list
the Thomas J. Langhorne and Company Radio Parts and Manufacturers at 316
Commonwealth Building. In 1927 and 1928 the Company is listed as the
Langhorne Radio Company. The 1928 listing has a C.S. Finley as an associate. No
mention of Langhorne. There is no listing in the 1929 City Directory.
Therefore the company was in business only from 1924 to 1928. There are no
articles mentioned in the indexes of the two Portland, Oregon newspapers
the Oregonian and the Oregon Journal." (Thanks, Art! Editor) The first RF
stage is tunable with the first of three dials. Not a hybrid. Very long set with
engraved panel, but no brand name. Based on the tube sockets used on
one of the only two sets known to exist, they were made in early 1925.
Buit each IF says "Langhorne Radio Company" which places it in 1927 or
28. |

coils were a new principle in late 1927. Two "D" coils face each other
inside the case. Shown also in American Radio Co. Catalog #117, Pg 37, Kit

Based on the Le Peer
"Essential Kit" & consisted of one Oscillator and four RF
transformers. Very unusual as it used a double-detection in the second
detector stage. Used "D"-shaped IF coil inside a moulded, moisture-proof
bakelite case to reduce coupling effects. "D" coils were a new principle
in late 1927. Two "D" coils face each other inside the case. Could be used
with loop or outside antenna when used with the optional Le Peer "AC"
coil, an additional $2.10. Shown also in American Radio Co. Catalog #117,
Pg 37, Kit Only, Nov 1927 [X]. Retail price was $27.50. American sold them
for $16.50. Called the "ER-9" and the "AR-9" in the
same American catalogue. Very small ad in RLG,

This nine tube super is
just a modification of the eight tube set of a year earlier. Many of the
physical attributes are the same. There are two potentiometers on the back
of the baseboard, for example, rather than the four on the Eight. One
extra IF was added to make this set a nine tuber. Five air-core IFs used
under-panel in this installation. The Oscillation Coil ("Fixt Inductance")
found at the far right of the basebroad, looking from behind. Acme audio
transformers ("Model MA-2") recommended here. Lincoln Quality Products are owned
by Rex Laboratories, Inc. at 341 The Arcade, Cleveland, Ohio. |

Remler parts. Probably built by the "Long Radio
Works" by brothers Les or George Long on the family farm on Rural Route 1
(later renamed "NW Long Road").
This location was 20 miles west of Portland, Oregon or 1 mile north
of the town of Cornelius, Oregon.
They were in radio business from 1920 through the late 1930s. Info from Art H. Redman email
(Portland 8/05): "Thanks for
the pictures of the Long Superhet and Langhorne. I would of got back to
you sooner but first I had to make a trip to the Mulnomah County Library
to find some information. The Long Superhet looks different than most Long
Battery sets than again its not a TRF. The blonde cabinet is unique. The
dials appear to of the common type available dials in the late 1920s.
There are no articles mentioned in the indexes of the two Portland, Oregon
newspapers, the Oregonian and the Oregon Journal." See Note 28. See Remler. |

CRCB introduced this set
with blueprints dated February 19, 1926. Operated at 35KC [8575
meters]. Has "Unit" numbers 1
thru 5 stamped on coil labels. Unit 1 was the Oscillator Coil. I believe
there were four different labels for the IF cans which may help date the
radio. The first from August 1925 to February 1926 were stamped into the metal can. The second series of labels from
February 1926 to late 1926 were rivetted metal labels with the painted
words "UNIT #" and a blank spot for the number to be painted on it. The
third was similar to the second but a painted word "TYPE" was used and a
blank spot was available for the letter & number. Lastly, from early
1927 until the shape of the IF changed in the Fall of 1927, on the 201A
cans, the area that was left absent of paint before was filled in and the
TYPE letter and number were both void of paint [reverse] across the bottom
of the label. See picture examples. WHen the new higher frequency IFs came
out in the Spring of 1927, the model numbers changed. They had been "M-1" thru "M-5". IN
1927 they became "HW1" thru "HW5". These designated them as One Spot IFs.
Located at 39th and Yates. 7x28 inch panel. |

IFs are "Type HWS". Duane
Bylund discovered the IF peak at 490 KHz. IF transformers each have a
bandwidth of about 30 kHz and they peak at 489 kHz, 503 kHz, 488 kHz, and
492 kHz, respectively. The filter transformer (HW-2) is physically much
different than the other transformers but it has similar electrical
characteristics. The gain on these transformer stages is about 1/3 of the
gain of other sets I have measured (possibly due to the operation near 500
kHz with a 01-A tube – these transformers would probably work better with
the type 199 tubes, or possibly even screen grid tubes). Radio News for
December 1927 has scheme. By this time, their address was 2524 G Federal
Boulevard. 7x26 inch panel. |

The
first two stages, used as untuned RF amps, were 199s. Used 6 - UX226s, 1 -
UY227, all 1.5 volt AC tubes, and 2 - UX199s run on 1.5 volts AC, also.
This set is designed for use with a specific power supply shown in the Nov
1927 CRCB. The PS schematic and layout is shown on page 105-106. It used
two tubes [280 & 874] to develop the filament voltage [1.5 AC] as well
as the B+ voltages. It also had an additional power audio stage that used
a 171. New MM AC IFs that are flat on the bottom, arched on top, and
aluminum. [The IFs for the battery set design was a special One Spot Tuna
Can style.] Tyrman double-drum dial. CRCB Jan '28 has operating the
International One-Spot. H-C

This is a Lacault
Ultradyne L-1 knock-off kit.
"…parts designed and tested by N. E. Borch, internationally known
radio engineer." "These sets are going like hotcakes." Input and Oscillator coils look
identical to Phenix coils. Transformers are black rather than the Lacault
maroon. Exactly the same ad
was published in June of 1925 in Radio bu the price had gone up to $30!!
Still listed in RTD, Aug '25.
Interesting the address [at 858 Pacific Building in San Fran.] in
the ads is the same building as Baldwin-Pacific at 441 Pacific
Building. See Phenix

The six honeycomb coils,
which make up the IFS, are connected to three variable capacitors with
dials at the back of the baseboard. The Tropodyne concept is similar to
this. The whole radio is breadboarded with two front panels of different

At first glance, this
appears to be a Receptrad, but it is a McDonald. On each IF, it says
"Distributed by W. E. Fuetterer S. & S. Co.". Has four similar looking McDonald
cylindrical IFs & filter.
Used white porcelain based tube sockets. Has seven Pacent rheostats
across the front panel. Taken
from the eBay description:
"This radio was distributed by Van-Ashe Radio Co., 208-10 North
10th St. St. Louis, MO. It
was designed by George W. Van Sickle, Radio Engineer. This unit featured Haynes-Griffin
IF, Input Oscillator Transformer Components. The IF is 30 KHz." "It has 2 Faradon UC 487
capacitors. It has Dubilier
Mica Capacitors patented July 6th 1920. It has 2 Remler gear driven tuning
capacitors." "I have a
partial schematic & detailed description of operation of the radio
that was in an advertisment in a St. Louis newspaper. But this paper is in very poor
condition." Because of the
newspaper ad, it might have been distributed by Van-Ash after the labels
were put on the IFs. It
is 36" wide, 10" deep, & 9 3/4" tall. Sold 0205 on eBay for $307. |

Earliest sets in 1927 had two typical numbered dials. Used the Northern Electric R215A
"Peanut" tube, which is the same as the Western Electric 215A. Uses 4
stages of IF (not typical) and 3 stages of audio, which leaves 1
oscillator, and 2 detector stages. Used wooden module under bakelite
baseboard similar to the RCA catacomb but with separate tube sockets.
Shown in a 'Deluxe Jewel Box" solid walnut cabinet. This set looks more
like the later models. Very different from the "Scout". Used a
series-parallel filament circuit for the 1.1 volt tubes on a 6 volt
source |

Complete
kit only. Had no cabinet nor tubes. $ 120 with connecting cable &
plug. Earliest sets into 1927 had two typical numbered dials. Used the
Northern Electric R215A "Peanut" tube [$3], which is the same as the
Western Electric 215A. Uses 4 stages of IF (not typical) and 3 stages of
audio, which leaves 1 oscillator, and 2 detector stages. Used wooden
module under bakelite baseboard similar to the RCA catacomb but with
separate tube sockets. Mercury History brochure says the 1927 model had
"detachable tuning coils" [plug-ins] at each end of the baseboard so they
might be changed when later development comes on lower waves, but
delivered for the "present WAVE BAND" only. Other coil sets were expected
later. But that same catalogue offered coils up to 2000 meteres for $8 per
pair. Most chassis had variable capacitors surrounded in clear bakelite to
keep dust out, but not all. Used a series-parallel filament circuit for
the 1.1 volt tubes on a 6 volt source. Set is just 7 inches deep. |

Two different models of
radio panels and two different cabinets.All "two control" sets show Klipish dials. Used the Northern Electric R215A
"Peanut" tube, which is the same as the Western Electric 215A. Uses 4
stages of IF (not typical) and 3 stages of audio, which leaves 1
oscillator, and 2 detector stages. Used wooden module under bakelite
baseboard similar to the RCA catacomb but with separate tube sockets.

[plug-ins] at each end of the baseboard so they might be changed when

December 1928 catalogue. Used
a series-parallel filament circuit for the 1.1 volt tubes on a 6 volt
source. "H" cabinet similar to the "D" with a flat bottom and a circular
medallion at center of the end posts. As of Dec 1928, address: 447 Yonge

The first "one-spot"
superhet RWI described in its pages. Frequency changer uses just one tube.
I believe the IF is 100 meters...2998 KC. RWI - July 26, '24 - P6 -
Followup Theory: "The Metaform Receiver has some advantages over the
Neutrodyne and the Super-Heterodyne. First, greater amplification...per
stage of RF because the RF amplifier, used with th frequency changer,
amplifies signals of only one frequency" and, therefore, doesn't have to
amplify all others. It has a "sum-frequency" like the Remler Infradyne and
a few others. The others have "difference-frequency" mixer. Most work on
the lower "difference" as the "sum" results in a higher output from
heterodyne process; thus; more accurately, a one-spot. RWI - July 26, '24,
"Another advanage in common with the Super-Heterodyne is the simplified
control in tuning." Any
number of tuned radio frequency stages still result in only two tuning
controls." Thompson was a senior at Lehigh University when he developed
this set. Did he go on to develop others and create a Thompson radio
company?? This information taken from the July 7. 1928 RWI issue, p3. See
"Thompson" below. |

RN - Nov 1924. RB - Nov
1924. PR - Jan 1925 - P88 - Ads. Advertising gone by April 1925, but
Lakeside and Microdyne references through Fall 1927 ?? Used IFs &
choke coil. Used only two IFs. Microdyne "story" in Radio Age Dec '24,
P64. Says "$160 complete" wired (??) and "$97.50 in knockdown form"!
Apparently, as soon as the Luetz trial ended, these were only offered as a
complete kit. It appears the Lakeside firm built up the kits. Promoted
thru Feb '26 - PR "What's New??". Called a "knockdown" in RTD, Aug
'25. See Lakeside Supply Co.
Also, see "Stephen". The Microdyne bakelite IF case was used to house the
Hammarlund RF choke in Sept '27.
Apex advertised in 1922 in RN. Address 1410 West 59th St. in RTD,

From eBay seller: "I can
read the following on three of the transformers "NO 83-A RET OIL". I
suppose they may be oil filled? I have original blueprints that go with
the auction that say "Super-Heterodyne Radio Reciever N.E.T. & T. CO.
Engineering Dept, Boston Dec. 4 1923" The blueprints show "83-A RET" for
the first 3 transformers and 222-A INP TRANS for the 4th. The blueprints
do not match this radio exactly, as it is a 6-tube set, and other minor
differences. The front panel measures 24” wide by about 12” high, and the
inside cabinet is 7.5” deep. Inside cabinet and removable lid is lined
with sheet copper. There are a couple of extra holes in the panel; I don’t
think there was anything ever mounted in them because the sheet copper is
visible through the holes. Someone might be able to add a jack or switch
in those extra holes and make it look nicer. The meter is not the correct
meter." This set was found in Utah where it was auctioned on eBay
8/2007. |

Designed to use the WE215 "Peanut Tube" - Filaments in series - Volume
limited by these tubes. Output is fed to the WE Power Amplifier (14A or
10A) for better volume. Design for both antenna & loop operation. "It
is believed that their receiver is known as a double detection system and
is constructed on the Hammond patents. Their receivers are only sold for
commercial purposes and are not available for amateur purposes (from

One of the earliest to use such a high IF, 600 meters/500
KHz! This frequency-changer
couples into the antenna circuit of a separate TRF, Neutrodyne, or a
Single-Circuit "blooper" receiver.
RB, Aug 1925: "The
object in using 600 meters is to place the intermediate-frequency
amplifiers above the broadcasting wavelength bands to avoid
interference." See Eastern
Coil Company above for main coil. RB June 1925 has construction of Freq
Changer (Part 1). Aug '25
issue of RB (Part 2) shows how to use the "Frequency Changer" with
ordinary TRFs. Schematics are shown for coils to hook up TRFs, etc. Care
must be taken to not short-circuit the 45 volt B+. Could be used with long wire
antenna and the tap switch on the front panel. Terminhal posts are
available for a two wire loop antenna as well. Radio Review, Nov '25, P9:
Five page construction article with schematic. Barawik for Fall '25 (P21):
Marvelo parts, $ 29.95. RB-Mar '26: "Complete parts /engraved panel
$37.50". The O'Connor & Company promoted "Super-Heterodyne
Headquarters Since 1923.".

[I designate this the
Model "L - 0".] This is the
ORIGINAL Ultradyne dated Feb. 1924. Lacault brought in many stations from
over 1,000 miles distant, using a 3" coil with 72 turns in the secondary,
but "NO antenna, loop, or ground" was attached. Shown in the 1926 "RN
Superheterodyne Book", it has 6 tubes and no audio stages. A 2-stage amp
was presented in a second article in RN (date unknown). Schematic in this
publication shows a long wire antenna and ground as is the December 1924
schematic. Mar '25, Radio Broadcast, tells how to add a loop to this set.
Because the company had not been formed yet (June '25 as you noted), this
was an instruction for a homebrew Ultradyne. RN Superheterodyne book tells
how to wind the coils & IFs.. Webb, "100 HookUps" book (Note 23 - Dec
1924- 3rd Ed. - Page 55) says IFs at 2600 meters/115KC. The pictures in
the article in this publication, however, do show what appears to be a set
of bakelite "tuna cans' that look an awfully lot like the ones sold by
Phenix later! Lacault called
the method of heterodyning the "Modulation" method, where the modulator
tube has no direct "B" battery on the plate. He also called it the
"Metropolitean Method" (Radio Topics, May 1924, p11). RN, Feb '24, P1058, Construction
& Scheme. Mar '25, RB,
(P907) tells how to ad a loop to this set. The set in the 1926 "RN
Superheterodyne Book" (See Note 21) has 6 tubes and no audio stages. A
2-stage amp was presented in a second article in RN (date unknown).
Recommends UV201As and a 216A or "E" tube (VT2) for the oscillator.
Lacault was amateur in 1911.
During WWI, was in French Signal Corps as apparatus designer. Worked later on transmission of
pix by wire. Lured to America
around 1920. Gernsback liked
him and made him technical editor over others who had been with Radio News
longer. Left RN when he
introduced the Ultradyne thru RN in 1924. Phenix Radio went bankrupt by the
end of July, 1926. Started
Radio Electric Laboratories [REL] immediately after Phenix was out. See
Lacault, Madison, Ray-Dee-Artcraft, Radio Electric Laboratories (R.E.L),
Strobodyne, and Ultradyne. Also see Marathon and Sypher Mfg. Thanks David Willenborg for his
help with Lacault. 7x24

Used the Precise
Super-Multiformer "1700" and other Precise parts. Very differently shaped
from most Supers. Panel is only 14 1/2 inches wide and 10 inches
tall. Benjamin introduced an
eight-tube socket panel specific to this radio (X). Front panel designed
to utilize two meters across the top. Fourteen pages of construction in
PR. D. T. W. (Tobe brand)
loop recommended. Shows McLaughlin, appears very young. Unique 10x14.5

Might be a three-dial set. RWI, August 15,
1925, P19: Schematic has complete parts list and details. The variometer
is to be used to tune the wavelength. IFs designed at 50 KC. UV201As
should be used, each at 10 ohms. |

This is the same three-dial Super as shown in the
"Baby Super" above with additional stages for DX'ing. Used a crystal
detector rather rthan a tube detector, so, the radio theoretically is a
nine tube set. Schematic also found in January
2, 1925 RWI with detailed parts description. |

This is two tube mixer
only is of the "sum-frequency" type, used by only a few Supers like the
Infradydne as a One-Spot receiver. The RF stage tube is a Screen Grid tube
while the oscillation stage "can be a 112". Otherwise, it wouild be a
UX201A. This mixer is to be used for Short-Wave reception (15 to 135
meters) and pulls in the broadcast band (200 to 600 meters) without
changing condensers or coils. Mixer output possibly in the range of 70 KC
is indicated. This circuit
might have been incorporated into many homebrews after the Summer of 1928.
Watch for two sets of two small, ganged tuning condensers with a larger
condenser placed between the two sets of two. Two variable coils grace the
baseboard, separated by one of the pairs of ganged, small condensers.
Herman Bernard was the RWI Editor at that time. |

|
|
|
"Set
of 4 Super-Heterodyne Neutro-Transformers with complete instructions for
building a six tube DX receiver."
It's based on 6 tubes, but without audio amplication. Used 1 Input transformer and 3 of
the Ray-Dee-Artcraft Super Heterodyne Tuned RF Transformers Type
10-A. Wound with #24 wire
rather than the typical #32.
"Having windings of large wire the distributed capacity is
extremely low, thus increasing the inductive value and lowering the
radio-frequency resistance, a condition so very desirable when long wave
transformers are considered. We know of no other Super-Heterodyne
transformer constructed in this manner." IFs set at a "Neutrodyne" angle on
the baseboard. Kit was $35. Ad in RJ, Nov '24, back cover still mentioned
Super Het IFs and parts. |

Note a multi-tap switch
on the left end of the front panel between the main tuning dials; used to
tune the long-wire antenna. A minimum of four taps. Used Modulation System
from Lacault, found by noting that there is no plate voltage on the
Modulator [Mixer] tube. Four 11-plate condensers on front panel to tune
each IF stage are pictured in article. Munzig says they are optional as
the IFs are efficient enough to leave them out. Schematic does not show
them. Spacing between each IF has to be three inches to keep it from
having to be shielded. Thus, the long panel at 36 inches! Used 201As in all sockets except
the second Detector, sixth tube in. Both Oscillator & Antenna coils
are lying down on the baseboard and both are hand-wound, shown in the
article. "Can use loop, but with less intensity." See "Phenix". |

IFs tuned to 47.5KC or
near 6000 meters. Used RCA 1716 IFs. Set used isolation thru the use of
metal dividers between IFs as taught by Armstrong at Radio Club of America
meetings. Designed for 201As, but UV199s, WD11s, and WD12s can be used.
Eltz demonstrated his Super in front of the Radio Club of America using
WD11s. In late 1923, Eltz was Radio Sales Manager for Manhattan Electrical
Supply Company (MESCO) in New York City. Worked with Armstrong on the
"Super-Regen-Het" (See Armstrong above). Another scheme: RB Sept 1924. ??

Standard 1923 receiver
construction. Three separate cabinets were used. First cabinet [about 12
inches long] was the Tuner-Oscillation section. The second [also about 12
inches long] was the Frequency Changer section. The third [about 8 inches
long] was the audio section. In the first section, the schematic showed
how regeneration could be added if the builder wished. Said it made the
set harder to tune, however.
It had two tubes; the oscillator and the first detector. The second
cabinet had two movable 250 turn honeycomb coils for energy transfer. It
held three tubes, all in the IF. Recommended RCA 60 KC IF transformers.
Construction of the IFs came in the March 1924 issue of Radio Age, P11, if
you wanted to build your won. The audio section was shown as three stages,
but no further info was provided. Rathbun said 199s would work, but
discouraged it. RA, January 1924, P11,Construction and p10 for the layout.
Schematic in Radio Age, June 1924 on page 20. Also, Radio Age Annual for
1924, p74. Could work on a long wire or loop antenna. See details above

This is about the first
homebuilt super using 199 tubes. Used RCA 1716 IF transformers. General
Radio variable condensers were recommended. Variable caps were used to
tune each of the IF stages, but likely not from the front panel. Pacent
Coils and Pacent parts for Roberts Super in RB - Aug '23. His original
super for this article had only two IF stages, making the set a 5 tube
arrangement. The filter stage ahead of the IFs is a pair of DL 750
honeycomb coils, shunted by a .001 variable capacitor each. This is the
first circuit described in Robert's article. See "Roberts" for details of
the other superhet.featured. |

This might have been
Receptrad's Model A. All others found are somewhat different. The Barry
Receptrad is called the Improved Model B and is very similar to all others
found. Article by Allan C. Forbes called "How To Construct A
Super-Heterodyne Set". Used Radio Receptor Receptrad IFs, numbered the
same as the RCA transformers, "1716". IF used "Herring Bone Windings"
which was patented and used by only RR. IF is of commuted iron called the
steel core type. This
receiver is different from the typical Receptrad as it has a tap switch
between the tuning dials and only five filament controls across the bottom
of the front panel where all others have six with most sets having them
above the filament controls.I believe the fronty panels were engraved to
order like in the case of the Dean Receptrad. Most other panels are 8x40
rather than the 7x39.5 inches of this early model. [WOW]. See Dean Receptrad above. |

From Dale Davenport. Only
known surviving copy of a low production set manufactured in Fort Smith
Arkansas in 1924.....obtained from Jimmie Barry, who built them.
These were sort of thin
"knock offs" of the Victor Greif Receptrad design. (This one won the Hauck
award in 1994 at the last ARCA Convention) The Jimmy Barry set uses Radio
Receptor IFs as well as audios and is a permutation of the Victor Greif
design. The sub panel
engraving says: "IMPROVED SUPER HETRODYNE" (sp), "Designed by Jas. A
Barry", "1924". The front panel engraving says: "MODEL B IMPROVED
SUPER-----HETRODYNE". Berry once told Davenport the parts were purchased
from and the panel / sub-panel engraving / drilling were done by Sterling
Radio In Kansas City. To the
best of Barry's recollection, production may have totalled less than a
couple of dozen, but they were "designed", built, and marketed [under
RCA's nose!]. Given the small
community (Fort Smith) where they were built and sold, Davenprt believes
it's a reasonable figure. If a serial numbering system was used, it must
have been by a paper tag or some such, as none is evident now, Davenport
adds. This single surviving example was originally sold to a state
legislator in Oklahoma in a town 30 or 40 miles to the south west of Fort
Smith. See Sidebar: In Fort Smith, Arkansas,
fifteen-year-old Jimmie Barry signed on WGAR at 5:00 P.M. each day: "This
is WGAR, the Southwest American station, located at Fort Smith, Arkansas,
the Playground of America. We have just come on the air, and we wonder if
anyone is listening." He would call names of various set owners and ask
whether they were home yet. The telephone would ring, and someone would
say that the program was coming in fine. When a person called and said
that he was having trouble with his receiving set, Barry would announce
that fact on the air and promptly lose most of his listeners. They would
hurry to the home of the owner of the defective set to help with repairs.

"Type 600" peaks at 6700
meters - 45 KC according to QST, Dec '24, P9, Transformer "Type 600"
statistics only. The kit
is... "Type 600 IF", "Type 610 Tuned Stage Transformer", & "Type 620
Coupler Unit" [a variometer]. The 600 was iron core and 610 with outboard
condenser attached was air. Advertised May thru June 1924 as "Remler Radio
Mfg. Company, San Francisco-Chicago". Radio, Jan '31, P20: Remler
Super-Het History. Elmer Cunningham, who had made a mark in the radio
world in the manufacturing of Cunningham brand radios tubes, founded
Remler in San Francisco in 1918 along with Thomas B. Gray and Ernest G.
Danielson. Cunningham came up with the name "Remler" for the new company
by spelling his first name backwards and adding an extra "R" for "radio"
to the end of it. They started by making radio parts, sockets, switches,
and other small components. By 1922 Cunningham had dropped out and
although it's products were still branded "Remler," the company was taken
over by Remler's partners and called the Gray and Danielson Mfg. Co. The
Remler lab had been experimenting with the Super Het circuit since 1922.
In May 1924 they produced the first of their line of high quality
super-heterodyne radio receivers. The 45KC version was closed out,
according to an ad in the Chicago Salvage Catalogue, in summer 1926. The
Infradyne was right around the corner. See the many Remler hybrid sets
listed just below "Remler". |

Some slight wiring differences from 1st generation. Front and base panels
lengthed by one inch to add binding posts to the front right. The battery
on-off switch was moved to the right-hand side. There were additional
phone jacks placed on the front panel. The output jack are arranged across
the front panel, rather than vertically as is the 1st generation. One of
these disconnects the voltmeter from the radio's circuit so that flexible
leads with clips might be used to test the "C" battery, etc. If you find a
General Electric Wayne door bell transformer and a 201A tube socket for
the last stage, it is a modification to the last audio, which includes two
variable 25 ohm Cutler Hammer resistances and a 200 variable potentiometer
in the tubes filament circuit.
A nine volt battery is used in the grid circuit of that same 201A.
The 25 Henry primary of the door bell transformer in conjunction with a 2
microfarad capacitor completes the improvement for the high voltage (120
v.) audio stage. |

sold a 21 inch panel with the set.

Barawik brought together
these parts: Remler Superhet and the "Acre" (brand) cabinet has built-in
loop (in the cover) and speaker. What's unique about the radio chassis is
that it's just 5 inches deep. The design put eight 199-style "spring
sockets", mounted on a long, narrow bakelite strip, mounted over (with use
of Benjamin brackets) the IF and audio transformers; making the set very
slim. The tubes, due to the type of the sockets in the picture, might have
been "UV"-style. The case, which is 22x15x7 inches, has black leather
grained Keratol covering. Center tapped loop antenna is 21 inches tall
which is the cover for the case. Uses Hoyt voltmeter in the center of the
panel. Barawick advertised it again in the Spring of 1926 on page 13 (X).
Prices were the same. Barawik price: $69.50 plus $39.75 for case, tubes,
batteries, Utah speaker unit. Weighs 35 lbs in all. The case by itself is
$15.95. 7x21 inch panel. |

Michael Feldt has a
beautiful one. He says it's a small Infradyne (Don't think so ???). Another schematic in CRCB, March 1929, P152 (Note 14).
Advertised as the Superhet with "Unit Construction" which means the
baseboard and the metal sub-base for the IFs and tubes are rivetted
together. Only a very few wires on the bottom are needed to be connected
to complete the set, getting around the RCA patents. Those wires are shown
in the CRCB article. "Three shield-grid IFs. Entire RF, IF, and audio

R - August 1926 - P11 & 46 |
|
Designed by E. M. Sargent
and L. C. Rayment over a two year period going through over 500 variants.
Rayment improved the Infradyne enough that Sargent included his name
officially in Radio magazine in November 1926. This radio is a straight
Super Het; has no 5 tube TRF
conversion. Differs from the
September 1926 version in that it uses the Thorola doughnut-style coils
and Ameritran or Silver-Marshall audios. The radio was one of the first to
operate on the SUM of the heterodyning and not the DIFFERENCE, meaning the
IF module amplified "short waves [in the range of 95 meters (3490 KC)]
instead of long waves [10,000 (30 KC)] as in the typical superhet and no
harmonic. No long wave distortion or noises." Resulting in only one dial
setting for each station. The set uses 10 tubes: an oscillator, two stages
of RF amplification, first detector or mixer, three stages of 95 meter
amplification, second detector or de-modulator, and two stages of AF
amplification. There are six
UX201As and four UX199s, three of which are in the module. Parts layout
different than the Revised version below. Barawik,
Summer '26: $96.50 and
Oct '26: $83.15. Model 700 Infradyne Amplifier module lists for $25. There is the first Citizen's Radio
Call Book version. The only difference between the original and the CRCB
version is a Jones plug for battery connections rather than terminal posts
on the original. Randolph Radio Catalogue - Fall
1926 - P22 - Complete. Also, see Remloc Radio
below. See "Sargent Flivver". Also see "Infradyne" above and "Remloc
Remler Infradyne" below . |

Improved filament and

coils still used here; although, an ad for Camfield's Duoformers appears

Far right of the front panel has this: "American - Beauty" Under
that there is an engraved rose blossom and beneath that is "Custom Remler
Made" with Remler in larger letters. Under that is the word
"Superheterodyne". Panel is dark red [mahogany] with meter on right, front
half. Used 199s as with Remlers. Appears to be well made with a
sub-chassis of bakelite. No other information known. |

Remlers), and a Tyrman Audio Frequency Transformer and Tyrman Push-Pull
Audios. Tyrman transformer cans are eight sided with TRC logo on the top.
Due to the Push-Pull output, it had nine tubes. Might have used the
Silver-Marshall Oscillator Coupler rather than the Camfield 620. Harry Alter

Autodyne principle
borrowed from the Tropadyne developed by Fitch. Used a bridged oscillator
developed by Pressley and used in Silver's Autodyne Super. Used two tuned
IFs (Filter units). "Remler 610 IFs a must" as the Remler 600 will not
work in this radio. Two main tuning dial on the front panel might have an
additional two that would be used to tune the Remler Filter units, if the
builder improvised incorrectly. Used a homemade "Figure 8" coil. Text said
it was not easy to make. Look for it. Non-reflexed, non-radiating, &
non-regeneration. Original article from The Chicago
Evening Post. Also, see RN "Superheterodyne"
book. See Note 21 below. A panel of 7x24 is usable if you tighten up the
parts. |

My reprint of the
February and March 1925 articles has construction details, layout, but no
schematic. It should also be in the RN Superheterodyne Book. See Note 21.
Neat looking set with two tuning dials, five filament controls, two meters
on the front panel. Had a Jewel two-position volt meter; 0-10 and
0-100. Used 201As and Remler
parts. Two three-tube sockets used in March 1925 might differentiate this
set. Also, look for a single flashlight battery mounted to the baseboard
for bias. Used external three tap loop made by Mathiesen. Loop antenna
attached through a hole on cabinet top. Metal panels shield several
sections inside the radio. Fall '25 Barawik catalogue ($99.50 with dual
meters). The outward appearance of this radio is the same as the Spring
1926 version, but the layout is different. "The Buy of a Lifetime at $125
(complete)". Taken from my copy of the magazine reprint: "How To Build
POPULAR MECHANICS’ Magazine SUPERHETERODYNE EIGHT. Reprint from February
& March 1925 issues. Mr. F. L. Brittin, Radio Editor of Popular
Mechanics Magazine and designer of the Superheterodyne Eight, will be glad

A good way to help
distinguish this kit from most is to see if it has one of these three
General Radio Oscillation Coils:
# 277A, 277B, & 277C. This is different from most remlers that
used the Remler 620 Oscillation Coil. Parts list recommended three small
Benjamin tube sockets and five large Benjamin sockets. Recommended one
Weston voltmeter. Used Remler IFs. Could have Thordarson, All American,
Lyric, or Karas audio transformers. Complete kit at $82.75 or $89.50
(special audios) sans cabinet and matched tubes at $2.50 each. RSOC is
addressed at 660 12th Street, Oakland. |

This is Scott's first
super and the duplicate he built while in New Zealand. Originally, he
built a straight Remler Best. Modified it to use two 600s and two 610s
each with a Remler variable capacitor across them. Provided better
selectivity. This is what appears to have made the Scott such a fine
Super. Information from the book, "E. H. Scott...The Dean of DX, Second
Edition 2002" by Marvin Hobbs. Remler "Type 600" peaks at 6700 meters - 45
KC according to QST, Dec '24, P9, Transformer "Type 600" statistics
only. The basic Remler kit
is...three "Type 600 IF", "Type 610 Tuned Stage Transformer", & "Type
620 Coupler Unit" [a variometer]. The 600 was iron core and 610 with
outboard fixed condenser attached was air. Used a small vernier on the
front panel for the oscillator circuit. |

See Remler "Sargent
Infradyne" (August 1926) above. This set is displayed at the Radio
Boulevard in Virginia City, Nevada. Web site indicates it is not original
due to the Thorola donut-style coils and that Silver Marshall coils were
standard. Not true. Camfield Duoformer (binocular)
coils, which might look like SM coils to some, were incorporated into the
second design version in September 1926. The Thorola donut coils were
standard in the August 1926 version. This is likely the CRCB version as it
does not appear to have the pair of terminal strips on the back, right
side of the baseboard and would have a Jone connecting plug. Presumably,
this company is a typical set-builder that assembled superhets for resale.
Because the name incorporates part of the Remler name and is in San
Francisco, it's possible it was a Remler company building their own
sets. |

RR, May '25: Excellent
pictures! Charles Caesar Ritz
was associated with "Science and Invention" magazine where this set was
first shown. In a huge cabinet, 38 x 28 x 8 inches, which RR, May 25, says
"Of course, it is not portable…(in) that it can be carried around by hand,
but is for automobile use in travel." IFs are 45 KC, therefore, likely
be Remlers. Used UV199s and 15 turns, 2 1/2 foot center-tapped loop. 8x36

This is about the first
homebuilt super using 199 tubes. General Radio variable condensers were
recommended. Variable caps were used to tune each of the IF stages, but
likely not from the front panel. Neutrodyne caps in the form of pennies
set 1/4 inch apart should be used on the 201A tubes as shown. Pacent Coils
and Pacent parts for Roberts Super in RB - Aug '23. One audio stage
[transformer] out of the detector. This is the second circuit described in
Robert's article. See "RCA - Roberts" for details of the other superhet

Three-dials. From the construction booklet,
dated 1925 by Norman W.Henley Publishing Co.: The three coils in the first
three stages are homebuilt as is the Filter transformer. The two IFs are
Rubicon Type "SR" transformers. Used seven UV201A and a 216A or UV202 in
the last audio. With a slight wiring change six WD12s and two UV201As can
be substituted. Front panel made of 1/16 inch brass with No. 34 sheet
brass shielding deviders between the second, third, and filter/audio
stages. inside the cabinet. Front of the brass panel is covered with 1/4
inch rubber panel for appearance sakes.Construction booklet has multiple
full-sized construction layout and schematics. Set is 10 inches deep. See

RN - Jan '25 shows
"Samson HW-R1 Helical Wound" IF (X). IFs peak at 60 KC or 5000 meters wave
length. The "HW-R1" IFs were also offered in September 1924 in 1000 meters
(300 KC) and 3000 meters (100 KC). Labels on the unit's bottom showed the
peak frequency. LAter ads did NOT promote anything but 5000 meteres. Ads
say matched transformers are better due to the helical windings and they
are never more than 87 cycles of each other and in most cases only 20
cycles. Good pix of kit in Randolph Catalogue, Fall '26. Barawick, Spring
1926: Kit $22.50. See Samson

This radio works more
along the principle of "Band-Pass" with the passing of frequesncies
between 40 to 50 KC. Used a multitude of small cylindrical RF Chokes and
small flat rectangular fixed condensers, all under the subpanel. Had
vertical eight-sided, double-wound tuned [filter] transformer near the
top, center of the subpanel. Had horizontal double-wound oscillator coil
near the top, center of the subpanel nearest the front panel. Had five
"output" transformers on the left side of the subpanel, looking from the
back. Lots of Amperites in filament line. Also called the "Samson Super'
in an ad for Shure Brothers: CRCB - Mar '27 -P214. |

First splash of this set
in The Radio (See "TR" in Legend K below) on November 22, 1924. Same
schematic as in Radio, Feb. '25 which used Samson "HW-R1 - 60 KC"
IFs. Published in the LA
Evening Express about the same time as TR. R, Feb 25: Full construction
article with layout. Also, see CRCB for Spring 1925 (Vol 6 #1) on P78 for
another construction article. See Samson ad in CRCB - Fall 1925 -
P79. RR, July 25, P23: "This article basically assembly
& wiring rather than construction." "IFs are primarily air core with a
very small amount of iron in them. Just enough iron to broaden the peak a
little." One of the few Superhets where the operator could adjust the
oscillator frequency through the front panel with the knob centered
between the tuning condensers.
With a 201A as the Oscillator tube, a grid leak of 30,000 ohms
should work. Its not critical. Even a 50 Kohm resistor will work
satisfactorily, according to text in RN (date
unknown).RN has construction info, layout, and
scheme. Used a three tap loop for regeneration in the first stage. Richard
W. "Dick" Cotton was an Engineer for Samson. Also see Note 21. |

Small set. It's a
modified impedance-coupled or also called "choke-coil" super. Decent
non-technical explanation of how Impedance-coupled amps work. Silver
Marshall 110-A ring and coil used as part of the oscillator circuit.
Designer liked the 200A tubes with 3 volt grid bias (not condenser-grid
leak) for both detector stages, but 199s could be used there. Samson
filter is laid out such that small fixed condensers can be slid on and off
its wires to tune various
output frequencies from 25 KC to 100 KC. Shielding for the oscillator
stage only is 30 guage aluminum. Used Remler variable condensers because
of no hand-capacitance. Designer used six 30 ohm rheostats for better
filament control, but scheme uses one. See "Impedance Coupled - CRCB"
above. |

Pressley, Chief Engineer, Signal Corps Radio Lab, Camp Vail, NJ, who was
then 26 years old and one of the highest-salaried government radio
engineers (RWI, Nov 8, ;24, P30)!
See Note 21. New
frontend circuit utilizes a capacity bridge that eliminates radiation from
the aerial. The first tube is oscillator and detector; thus, eliminating
complications of the second harmonic. First five tubes are WD12s abd the
last two are 201As.

RA / RN - Fall 1925 - 20 Page Book
with Construction Info, parts list, & scheme |

Information from the
book, "E. H. Scott...The Dean of DX, Second Edition 2002" by Marvin Hobbs.
After Scott returned to America, he had many requests for construction
info. Put together a 20 page book with parts list and blueprints. Charged
$5.00. Advertised it in Ra and RN in the Fall of 1925. This is Scott's first super and
the duplicate he built while in New Zealand. Originally, he built a
straight Remler Best. Modified it to use two 600s and two 610s each with a
Remler variable capacitor across them. Provided better selectivity. This
is what appears to have made the Scott such a fine Super. Information from
the book, "E. H. Scott...The Dean of DX, Second Edition 2002" by Marvin
Hobbs. Remler "Type 600" peaks at 6700 meters - 45 KC according to QST,
Dec '24, P9, Transformer "Type 600" statistics only. The basic Remler kit is...three
"Type 600 IF", "Type 610 Tuned Stage Transformer", & "Type 620 Coupler
Unit" [a variometer]. The 600 was iron core and 610 with outboard fixed
condenser attached was air. Used a small vernier on the front panel for
the oscillator circuit not counted in "Additional Knobs". |

Used
the R400 Series IF & Filter. Both IF & Filter units are shown as
R400s. Later the Filter was listed as the R410. IF had specially shaped
core and high grade silicon steel laminations. IFs designed for either
199s or 201As. Three IF and two Filter units were on the bakelite
baseboard while the tubes & sockets were on 22 fiber posts above the
IFs. Used two "Interchangeable Couplers". One as a Oscillator Coupler and
the second as an Antenna Coupler.
These don't appear to be the typical "Thor" Coupler. These had
special bases that allowed the changing of wavelength thru changing either
of two couplers, 25 to 150 meters or 220 to 550 meters. These had split
stators with balanced windings.Last tube ibn the audio was likely a 112 as
a 112 Amperite was described in the parts list. Barawick, Oct '26 had list
at $123.50. Their price $98.80. Shipping weight was 15 pounds. Drilled
& engraved 7x26 inch panel. |

Article tells how to tune
IF trimmers. Four stages of IF. Audio output is push-pull using 245s.
Power supply uses two 280s for 90 volt B+. Schematics include power supply
& connections. Sold cabinets also for the chassis. Called "A. C.
Shield-Grid 10" in Sept '29 CRCB & "A-C Screen Grid 10" in Nov '29
CRCB. (Radio - September 1929 - P?? -Complete). "According to Jim Clark's book on
Scott, the third version (with four 224 tubes) was not introduced until
March 1930. The fourth 224 replaced a 227 in the mixer (first detector)
stage. The first version of
the AC-10 was introduced in July 1929; the second version in November
1929. Superficially, the only difference between versions one and two may
have been that version 1 had a large dial escutcheon while version 2 had a
small dial escutcheon, which carried over into version 3." (From Tolbert
Prowell - email 2-19-04)
Panel 7x18 inch walnut. This is the last Scott

(shown in PR June '25) includes 2 "Two-Ten"s (IFs) which peak at 5000
meters (same IFs used in the 401 Unit), 1 "Two-Eleven" (Filter), and 1
"101B"(Coupling Unit) with instructions. RA - February 1925 - P62 -
IFs Only. These IFs did not work well and were replaced by about January
1926. (See January 1926 "Improved All-Wave" for details on bakelite IFs.)

Barawik (Fall '25) says:
"This circuit is a adaption of the famous Pressley [Bridge Oscillator]
circuit - much simplified, more effective, and with one less tube." "Will
not radiate, not even over slight distances of a few yards." IFs work at
60 KC. MIght be found with the aluminum square IFs or
the newer miscellaneous shaped IFs. Radio
appeared at the transition of the IFs. PR - July 1925 - P32 - Ad. RN, "Superheterodyne" book [Note
21] published details on how to build your own IFs, Filter, and Oscillator
coil. It also has a scheme and parts list, showing S-M 60 KC IFs and
Filter. Apparent construction
article appeared in NY Herald
/ NY Tribune on Aug 30, 1925.

Also, RN Jan '26 article. It has a scheme. There is a shielded
version and an unshielded version. See RN Jan 1926. Used SM "210 & "211" transformers (peak at 60 K.C.
Specifically, 201A tubes: 50 to
60 KC, 199 tubes: 60 to 70 KC) and "110A" & "111A" Special
coils. Another way to identify this set is to
look for the use of grid bias on both detectors is rather than the grid
resistor and condenser. That is, note the absence of a grid resistor on
the grid of both detector tubes. Silver
recommends 199s to the last stage which is a 120. If 201As are used then
the last stage is a 112. 201As will give better results. Indicates that oscillator circuit
is broad enough that the two main tuning dials could be geared together
for single control tuning. So, this set might have a single tuning dial.
If it has a single dial, it should use only a long wire antenna unless
modifications are made to the front end of the set (see RN,
"Superheterodyne" book test).
"New 1926" Barawik: "Two stages of RF amplification with special
biased detector and 3 stages of resistance coupled audio amplifier." "This
radio won the First and Second Place Prizes at the Chicago Radio Show"
says Barawick Catalogue, September 1926. |

Barawick referenced it as
the Model 712 in Sp & Summer '29 catalogue. Used 6 - 222, 2 - 201A,
and 1 - 112 tubes. Used two stages of 65 KC IFs from SM 210 long wave
transformers. These transformers were found to work well with the
screen-grid tubes according to the article in CRCB. Article said the low
IF benefitted over the higher IF (over 100 KC). "...the perfectly obvious
desirability the low I.F. to get great amplification and selectivity."
Used the Clough System of audio amplification. Most of the electronics is
covered by seven retangular, copper boxes. Barawik Cat., Sp &
Summer '29 says the 712 Unit (about 90% of the entire radio) is
"completely wired and inspected before leaving factory...". at $55.98. The
SM 700 two-tone brown metal shielding cabinet is $5.55 extra. |

This seems to be the
Rolls Royce of the Rolls Royce of Superhet Receivers! As a three-dial
Super, it used the Silver Marshal 112 KC IF module, the SM 440 Time Signal
Amplifier. The three-dials are the Oscillator Condenser, the Secondary
Condenser, and the Antenna Condenser, left to right looking at the front
panel. It is a Local/Superhet hybrid. A switch changes the Super into a
single-dial, one screen grid-tube local receiver. There is a feedback
circuit and a switch that makes the antenna circuit aperiodic or periodic
which aides in distance getting. Used four 327 and three 326 tubes.
Developer recommends a push-pull power amplifier on the output making the
set a 9 tube receiver, if added. Using a pair of 171s is slightly better
than one 210, while two 210s with low distortion is better than a single
250. Using two 250s has an extreme output. Oscillator is a modified
Hartley. See Dana Adams other superhets under the "Flexible DC" and
Flexible AC" immediately below. See Silver Marshall for more info on the
Time Signal Amplifier. Twelve inches deep. 7X24 inch front panel. |

IFs. Maybe didn't want to create conflict of interest. Sub-panel is 16
gauge brass and is 7x16. Brass shields were used to sepaarate various
sections of the radio inside the case. Adapted to a long wire outdoor
antenna. A hand-wound "loading coil" was used to compensate for various
lengths of antenna wire starting at 75 feet. |

Marshall Jeweler's Time Signal Screen Grid Amplifier Module and all
Screen-Grid tubes. Audio
stages are resistance-coupled. "First tube circuit consists of
regenerative …feedback." "A
novel feature…is the use of two meters, one a seven-volt voltmeter and the

Three-dial set! Switches
from 4-tube Regenerator to 9-tube Super Het. "One stage of TRF with
regeneration, a non-regenerative first detector, three stages of iron core
medium frequency amplification--from 30 KC to 60 KC--a non-regenerative
second detector, and two stages of transformer coupled audio
frequency." Three-part weekly
series in RWI beginning Feb. 6, '26 (13 & 20). Although brand of parts is not
specified in April '26 RN, developer used Silver-Marshall Oscillation Coil
and IFs. April '26 RN shows scheme & much more info. Ad in RWI March
6, '26, P2, and RN June '26 show General Radio IFs. Also see Note 21.
Schematic also in Secor's "Super Het - Which One?" - Radio Listener Guide
(No Month 1927). Quoted from Secor article (Publication unknown): "One of
the latest superheterodynes which comprises simply a few improvements in
the general circuit arrangement, coupled with one stage of tuned radio
frequency ahead of the first detector, and shielding, to increase the
range of reception, is known as the Fenway. On studying this circuit you
will see that you can utilize the features of this super?het if you
already own one, by simply adding one stage of tuned radio frequency ahead
of the first detector. Mr. Fenway in his superhet shields various parts of
the circuit, and those interested in these desirable features should
peruse carefully the articles which have appeared in various radio
journals. Referring to Fig. 3, the diagram of the Fenway superheterodyne,
you will note the antenna coupler. This may be any standard coupler with
or without a rotor which is not used, the proper size of variable
condenser being used to tune the secondary of course. Next for our
consideration comes the radio frequency coupler labeled L1 and L2. As
diagram Fig. 4 shows, this coupler “B” may be an ordinary variocoupler,
using the secondary or tickler as the rotor P, the secondary of the
coupler being tuned by a suitable size variable condenser, V. The
oscillator coupler with the three coils, L3, L4, and L?5, may be of any
standard form, or else constructed according to Mr. Fenway's
specifications, as given in articles referred to. The intermediate
transformers may be of any well-known make, Mr. Fenway specifying those of
the iron core type. (Likely S-M - Editor) This super-heterodyne requires
three tuning controls or variable condensers, and it is the writer's
opinion that the same results can be obtained with a nine tube lineup,
utilizing an extra stage of intermediate radio frequency (4 stages in
all), as pointed out previously."Fenway, 29 West 64th Street, NY. Moved in
Dec '28 to 831 Eighth Ave (across from Madison Sq Garden)...then known as
DX, Inc. Entire radio is
shielded as around inside of the case, top to bottom, and individual tubes
stage copper shielding. (I
bought this radio in August 2007 for $1750 including shipping from a
collector in New Jersey. He had it for some 15 years and knew the original
builder! Entire set of parts might have been bought from "Chas W. Down"
radio shop in New York. See ad.) |

Model "RT" must have been
"Radip Transformer". (St. James may have started as early as 1923.) QST, Dec 1924 indicates peak at
1200 meters (250 KC) (X).
Vacuum-sealed tube. It was said by Marvin W. Thompson, one-time
Technical Editor of Radio Digest Illustrated (1924, 1925, & 1926) that
Robert T. St. James matches the transformers himself rather than to leave
it to an employee (RDI, Jan. '27, Issue 2, P7). CRCB Spring 1925 (Vol 6
#1) and Fall 1925 ads show a taller glass envelope than show in 1927 ads.

IFs operate at 240 KC
according to Barawik September '26. Used the earlier (Fall 1925) style of
glass, air-core IF transformer without the red top. Barawik: September '26
and Oct '26, $85.60 St
James IFs described (Taken from an ad in CRCB Sept '26): Only one of its
kind. Two air coils, wound ina special mannerto reduce inter-turn
(internal) apacity to a minimum, are mounted on a glass rod. The coil
terminals are silver-soldered to terminal wires running to the transformer
terminals. The glass rod carrying the coils is mounted in a high
lead-content glass casing. The coils are then completely dehydrated by
athe repeated additon and subtraction of dehydrated air. The added
effeciency due to the complete absence of moisture must be experienced to
be appreciated... The
diameter of the largest coil used in the St. James transformers is
slightly under 7/8-inch. This unusal small size, together with the effect
of the vacuum and the shielding effect of the high lead-content glass,
combine to produce a magnetic field so concentrated that the hand may be
placed directly around any of the transformers while the set is in
operation, without the slightest de-tuning effect... With the intermediates operating
at 240 KC (hence the name, 2-40), oscillator repeats are reduced toa
minimum, and, with a total lack of inherent harmonics... 7x24 inch panel. |

**** "French translation
and American adaptation by R. E. Lacault" according to RN. Developed in
early 1926 in Paris. Four part series in RN: July, Aug, Sept, & Oct,
1927. First part is explanation of how the circuit works and is different
than other Supers. Three part series in RW: Sept 17 & 24 and Oct 1,
1927. The latter has schematic and parts list on P19. One stage of
TRF for 1st stage, making three tuning dials. IFs
are Madison [Lacault designed] tuned units. May or may not have the
Madison name on them. Used 7 - 201As & 1 - 112A or 171A. Sept 1927, RN
showed a scheme for an AC-DC power supply, using a single 210 tube. Three
metal boxes shield the tuning units. M & H Sporting Goods of
Philadelphia exhibited a working Strobodyne during Sept '27. S. Hammer
Radio Co. offered completely wired in Fritts cabinet for $173 in Sept. '27
[P9]. Also see Consrad. |

Supertone employed a unique type of early printed circuit. The
chassis was made from a Bakelite type of material and had traces milled
into its lower surface. These traces were filled with a copper paste for
conductivity, and components were connected to (and through) the filled
traces with small bolts and electrical eyelets. |

This is an Ultradyne
Knock-off. Same as the Phenix
Ultradyne L-1. The October ad
promotes Ultradyne. The Nov 1924
issue of Popular Radio has NO mention of Ultradyne (USE
both)! Lacault apparently stopped
them from using the name.
These are iron core where the original Ultraformers are air core.
These are matched using the wave meter method. Set of four Ultraformers
$20, one Oscillator Coil $2, one Tuning Coil $2. "Each set of transformers is
tested out individually in a set on broadcast wves before it receives our
stamp of approval." Sypher was making crystal detectors and radio parts in
early 1922. I have these
IFs. See Ultradyne
L-1. |

This seven tube set omits
the typical 1st stage RF amp. The right hand variable condenser tunes the
anttennna directly. The Oscillator used an non-variable Ellis "D" coil.
Used only two iron-core IF transformers and one air-core filter. All IFs
and audios are Halldorson transformers. Easy to spot. Walt S. Thompson,
Jr., possible developer. See
"Metaform" above. Used Halldorson IFs. See "Ellis Electrical Labs.". See "Halldorson" above for 1928

Six tube set. First Detector & Oscillator
combined in first tube. Very atypical. IFs are tuned by individual
variable condensers. Tunes from 2000 to 7000 meters. The homebrew IFs
shown in RN, :Superheterodynes" book were built with japanned silicon
stell. Likely, the Tropadyne
variable IFs had the same type of core. No grid leak on second Detector
stage as it was found to cause distortion decreased as the tube was
operated on the lower end of the characteristic curve. Only one audio stage. Later sold
by sister-company, Radio Specialty Company. Also, see Webb (Note 6) - P15. Sold for $60.50 in Kit form ^.
Also see Note 21. See Note 27. Tropaformer only $6.75. Split antenna coil means no
radiation [I believe that's Pressley's development].It is
regenerative. "Tropaia" in
Greek means change; "dyne" meaning force. It was said from articles of the
day that this six tube super performed better than a seven tube
super. "Knockdown" still
listed in RTD, Aug '25. Vincennes Phonograph Company of Vincennes,
Indiana, bought Radio Industries Corp just before Chtistmas of 1925 and
both became "The Radio
Industries Corporation (RRET, Jan '26, P67). Also see RN for November 1924
and the RN "Superheterodynes"
book [X] for more
details. 7x30 inch
panel. |

CRCB says first model of
7 tube super-het to use Screen Grid tubes (SP-122). Also known as "Screen Grid 7";
constructed in RN - Jan '28 - P764. The article in NYSRS has much detail
as to consruction including baseboard layout. I believe the oscillator ran
at 1025 KC. IFs peaked at 346 KC. Therefore, the beat frequency is
separated by 680 KC [as claimed in the text] so a station appears only
once on the dial..."One Spot". "IF amplification has a factor of 50
compared with 7" in previous typical IF applications. Camfield variable condensers
recommended (X). Used Webster
AB70 eliminator. RWI articles Feb 4 (X) & 11 (X), '28, Part 3 of 4,
Feb 18, 1928 (X). Ad in CRCB,
Jan '28, P203. Transformers
[different than the 8-80s used with 201As]: three RF 9-90, one Inductance
9-80, two AF 3-30, and one Output.
Tubes were UX222 Shield Grid
25 mA "B" current and
1.25 "A" current. H-C cat, Late Summer '27 $74.75. Jones plug allows
eliminator or DC operation.

A
5 tube adaptation of the Ultradyne L-1. Used Lacault's Modulation System
of heterodyning, where the plate of the first detector is at ground
potential (no B+ applied). Silver Marshall 110-A Plug-in Coil used for the
only IF transformer. Had homebrew Antenna & Oscillator coils. No
typical IF transformers used as it has only one stage of Intermediate
Frequency, through which the frequency can be varied without detriment to
any other part of the circuit.
Audio output used a large choke to accomidate either a 112 or 171
tube. The latter used if operator had a power supply rather than B
batteries. Construction also found in Radio New Amateurs' Handibook for
1927. Some info from David Willenborg. 7x21 inch Lignole panel which is
recommended for it, which is already drilled and engraved. |

This is a new company in
Chicago for the Ultradyne concept. This set is "all electric" using only
60 cycle AC. Separate power supply has 7x12 inch panel. Tubes are Sovereign AC. Used the original Lacault
"Modulation System". Has
first stage as tuned RF amp.
Both osc. & mixer are shielded. Uses Tyrman drum dial. See

Combines TRF & Super,
but not a hybrid. Four (4) tuning dials "which tune together" & six (6) pots! Can be set up as a 5, 6, 7, or 8
tube set. "Three tube Super with two stages of TRF amplification and any
form of audio which may be desired." "TRF amplification plus oscillator
action give all signals additional strength, regardless of distance. One
stage IF amplification assures full volume and a clear, pure tone without
distortion." "Complete kits for any kind Super may be purchased at prices
ranging from $7.50 to $20."
IF transformer is made in three frequencies (30-50-100 KC) and
schematics/layouts for 5, 6, 7, & 8 tubes for any type Super. WA, Oct 1924 ad: $16 for kit. Good
ad also RB, Oct '24, P530ish.

Published letter, in RN,
July 1927, from Utz about his 5 foot long, 30 inch deep, 200 pound set!
Covered 35 to 1000 meters. Could be switched between a regenerative, set,
a TRF receiver, or a superhet, using from 4 tubes up! RF and First
Detector have three ganged condensers with "proper verniers and
conpensators". Used a Western Electric 7A three tube amplifier [not shown]
for a total of 17 tubes!! Used 110 volt AC. AC filament wire ran through metal
tubing which eliminated the HUMMM. Scheme has limited values. Said most
parts were not standard, off-the-shelf parts. Used 300 foot outside wire
60 feet up. On speaker it
could be heard more than a mile away! One of a kind set at 93 Liberty
street, Westminster, MD. 72
inch irvory, gold and black panel. |

author's original story appeared in the New York "Evening World" September 27, 1924. H.G.
Silbersdorff was the writer of the article and discusses the layout, what
to do, what not to do, what types of tubes to be used, (301A or 201A).
There is a list of parts required to build this set as well as the
estimated cost of the materials.

Used six coils. First is
the "HetroCoupler", 2nd is the "Oscillator" Coupler, and then 4 IFs. IF worked at 88 KC, chosen because
it gave the "least trouble with harmonics". First mentioned in PR Feb '25
issue on page 190, the "What's New" column. Good construction in RR, May
'25. Recommended 7x26 inch panel, but a 22 or 24 will work according to
RR, May '25. Though Charles was Victoreen's first name, he was called
John, his middle name. See "George W. Walker Company" for more. |

I believe this radio
[#302] was built by the Victoreen Laboratory before the court order was
placed making manufactured superhets illegal. In any event, this is an
extremely rare, factory-manufactured Victoreen. The following taken from
the eBay description of 2004:
This radio has a nice engraved panel indicating “Victoreen Eight”,
and has a glued on piece of paper inside the cabinet identifying it as a
Victoreen Laboratory Super-Heterodyne with s/n 302! It is the only
superhet I’ve seen, aside from the RCA sets, that has had a serial
number. I did not take a
photo of this, but the back of the panel has scribe marks where the holes
were located for drilling, and it is also marked with the number 302! I
doubt that a normal builder would mark the back of the panel with a number
302, but I also doubt that the factory would still be using scribe marks
to drill every hole after making 302 sets. The antenna coupling
transformer is missing, the wires behind the loop jack have been cut off
and a small variable capacitor has been added, but everything else is
original. Address of the Victoreen Laboratory on the label changed from
7817 Carnegie Avenue to a pencilled in 1900 E 93, Cleveland. |

Arrangement of
oscillation coil changed to front, center of baseboard. George W. Walker advertised as the
"Merchandiser of Victoreen Products" and also called himself a "Marketing
Rep" for Victoreen. CRCB,
Fall '25, P166, Kit / Parts.
RN ad says each kit had 5 units: 3 - No. 170 RF Transformers, 1 -
No. 175 Antenna Coupler [for loop only], & 1 - No. 150 [Oscillator]
Coupling Unit. For outside aerial, No. 160 Antenna Coupler is required
extra.. Kit $33.50. "UV199 or 201A Type of Tubes may be used. A truly
Victoreen Feature. 'B' Battery consumption is remarkably low -- 8-10
milliamps, with Potentiometer at negative side." [Incidently, a bit later the Type
"171" IF transformer was introduced for specific use with the 199 type
tubes. Referenced in Rowan Radio catalogue of late 1927.] RN, Sept '26 says there is a
variable capacitor inside the case connected to the secondary of each IF
coil. The nut on the outside of the case changes the capacity to "match"
each unit to its peak. Also,
the "One Dial Master Control Unit" advertised in RN, Jan '27, P886. Seen in Spring 1926 Barawik, P23,
for $29.25. Complete kit $79.
7x24 inch panel.
According to AWA article [Ohio's Radio Industry in the 1920s] by D.
K. Owens on page31, Victoreen announced the formation of a company to make
(manufacture complete) Super Hets. "He produced a line of 1930 models, but
vanashed after that." Not
so! |

Lynch Power
Supply/Amplifier constructed separately. Major construction change is
inclusion of 1 mfd bypass caps in parallel with .5 meg resistors in
the B+.plate leads (to allow
higher B+) to allow adaptation of Lynch power supply/audio amp combo. The Sept 25th installment has the
lamp-socket power supply and audio amp for this Victoreen. Special choice of tubes stressed:
2-CECO type H detector, 3-CECO high mu type G, 1-CECO type A. Lynch says "It would be hard to
find a Super-Heterodyne which has given the home constructor more joy and
less trouble than the Victoreen…In almost every instance, the builder of a
Victoreen has been pleased with its performance from the beginning and the
ordinary buzz has been noticably absent." Bernard followup: RWI, Oct 2, '27,
P? Either 8x22 inch or
7x21 inch panel. |

19, 1922. The first "plug-in" transformer. "First on the market" which is
debatable as RCA advertised the 714 & 716 in the same RN issue as the
Vir Bren transformer was shown in an amplifier article. Transformer "DX-2"
(long rectangular design) peaks at 3300 meters. Location: 930 "D" St. NW.

Leutz (Note 7 ) - Fig.47 |

Has two IF stages (Note 7
- P79). Designed to use the WE215 "Peanut Tube" also called the "N" tube -
Filaments in series - Volume limited by these tubes. Output is fed to the
WE Power Amplifier (14A or 10A) for better volume. Designed for loop use
only. Leutz in his book "Modern Radio Reception" show how to convert it to
antenna, also."It is believed that their receiver is known as a double
detection system and is constructed on the Hammond patents. Their
receivers are only sold for commercial purposes and are not available for
amateur purposes (from "Modern Radio Reception", P79)." Used a lot of tube
& front panel shielding. Free from reflexing. First Super Het
installed in the White House in early 1924 ^^. |

Three dials. Double detection Super means it has a first and second
detector. This set is designed to receive code tones rather than speech.
Grid leak for the first detector stage is output of the oscillator
(through its grid circuit); thus, no pickup coil is necessary. All 8 tubes
are connected in series. Has numerous small panel lights to indicate the
tube is operating properly. All sections are shielded. Tuned grid
oscillator is used. If an amateur would build this set, it's recommended
to use a 30 KC IF and WD-11 or WD-12 tubes. |

"Three
stages of RF, oscillator, crystal detector, and two stages of AF are
accomplished…by reflex." Used
"standard type of (oscillator) coupler." Designed for 199s. The 3 IF transformers are DL 75
turn and DL 350-400 turn honeycomb coils, tightly tied together for
close-coupling. Good AF transformers used to reflex. Also, schematic &
