Thanks Matt. Publications that are in the public domain are ok, such as schematics.

I want to make this a simple picture search for 20's supers, linking in the better descriptions and more detailed information such as on Duane's site. Also a few links back to here might help with all of the pictures that are missing now.

I have begun contacting interested parties. If I miss anybody, don't hesitate giving me a PM or contact through Russ' Old Radios. I would post my email here but I already have enough friends in central Africa (still waiting for my million $).

Russ

That is all incorrect. You can search many ways (detailed search). Membership is worthwhile, and is done by snail mail to avoid jokers, pretenders, or outright crooks. Anyone who collects radios and is not a member of Radiomuseum is shooting theirself in the feet. Long after other information is lost or deleted, RM will be around, as it is supported by a well-funded foundation.

Best of luck in the Roaring 20's Superhets endeavor. I look forward to seeing the end results.

FWIW, I agree with you wholeheartedly regarding certain RM zealots and picture theft!

BR,

Terry

I am going to begin working on the 20's Super ID Page.

The Microdyne looks great! I enjoyed reading your article on it.

I have made a great deal of progress on the super-directory:

https://www.russoldradios.com/1920s-sup ... odyne.html

Thanks much to Rick, Duane and Kent.

The page is large, probably too large for dial-up,

Russ

It seems that Duane was correct about the original meter on my Victoreen AND Harry managed to find one - all I had to do is install it.

https://www.russoldradios.com/blog/supe ... -victoreen

This radio is still one of the best early supers that I have tested and the meter that allows the user to monitor both A+ and B+, along with the simple controls, makes it probably the most user-friendly.

Victoreen Superhetrodyne.
Just got this one. Complete, with 2nd audio transformer replaced but not wired F to A-. After fixing that and some broken solder joints it plays really well. The 2nd audio is way too loud and a bit harsh, sounds better on just the first audio jack.

The radio is not exactly like the often found schematic, modified to eliminate the C battery and detectors and oscillator filaments all controlled with one rheostat. Does not have a switch for wire or loop; instead a switching jack is used.

Controls are (left to right) IF tubes filament; oscillator tune; potentiometer (volume control); frequency tune; AF amp filaments voltage. Rheostat on the inside sets filament voltage for both detector tubes and the oscillator tube.

Plays nice and is easy to use.

Here's an interesting vintage photo showing someone's version
of a Leutz L, article says the set has 14 tubes.
The cabinet design and the GenRad knobs make it clearly Leutz.

Here's the other end of the spectrum, a 5 tube superhet with crystal detectors.

:lol: :lol: Feel free to move it somewhere else if you want to. But can anyone name an early superhet or just about any radio that doesn't have at least one thing in it that was made from Bakelite type material? Ran across Leo's picture while looking at some old newspapers. BTW the 5 tube 2 crystal super schematic was from an Ohio article in Oct 1924. Anybody have one?

edit: Baekeland was also an avid early motorist and wrote a series of articles published in Horseless Age about his adventures. Those articles were also published in book form as A Family Motor Tour Through Europe that can be read here: https://archive.org/details/familymotortourt00baekrich/page/n7
more biographical info here:

Oh no I meant that it was perfect for this thread as both Baekeland and Armstrong (The inventor of the Superhet) are from Yonkers, NY.

Here's something I picked up a few months back. It's a power supply/amplifier for a 1928 Scott Worlds Record Shield Grid 9 superhet but it's a more modern version then the more usually seen square box power supply/amplifier.

Image
Tubes: UX-281, UX-281, and UX-250.

I figure this unit was made just before or during the early production of the Scott World's Record Shield Grid AC10. I'm planning on completely restoring the unit both cosmetically and electrically.

Great find. Mine looks like yours, I got mine at the Henry Ford auction back in the mid-90s. These are rare, I'm glad you will be restoring it!
