The 1955 Emerson model 838 used subminiature tubes as the converter, IF, and 1st Audio while the output stage used a pair of transistors in push-pull.

When FM stereo was added to German sets, the multiplex decoder was often solid state.

I will surely check my 1950s and 1960s radios and see what they have inside. What fun.

Emerson actually made two hybrid versions, basing them on the 4 tube cabinet and chassis from the 747 model of -I believe- 1953. The 1955 model 838 and 1956 model 856 -as Dave said- replaced the audio output tube with a pair of Transistors. The difference between them was simply front panel cosmetics.

The A supply battery was changed from 1-1/2 to 4 volts. The entire battery compliment was supposed to last longer, given that the audio output was the biggest user of current with a tube, but not so with Transistors.

Automatic Radio's Tom Thumb did the same thing, basing their 3 tube 2 Transistor model TT-600 after the original 4 tube model TT-550.

Top shelf, left side, Emerson 4 tube 747, center and right, Emerson 856.

Middle shelf, two centers and upper right, Tom Thumb 4 tube 550. Two lefts and lower right, Tom Thumb 600.

Upper rear, two Regency TR-1's thrown in for good measure.

Thanks Colin!
It is a very scarce set, prototype maybe?
Most of the GR-711 models did not have an easel stand, they used a wire handle / stand.
The red plastic case is from a completely retooled mold.

Welp this dont fit in here probably but I soldered this Elenco AM kit together. Its is a transister radio. In a Frankenstein sorts of wayIt was fun to solder and easy. I got it so I can experiment with different antennas I want to build and other components. I think.its great!

Rob, I think your Elenco kit fits perfectly in this forum. It’s a transistor radio and it’s part of your collection. I like it.

I have several radios from the 1960s to early-1980s. I will have to take pictures
