Just picked this radio up today but having no luck searching web for schematic. Circa 1929/1930?
Tube set includes UX280, UY247, UY227, UY235, UY224 etc…AC powered with 10 inch speaker I think…

I looked up the model S42 and it looks very similar,especially the photos of the chassis.
I did not find the schematics. It might be very close,but the tube line up is different.

Does this G E Model S-22 look something like yours?? Some pics of you Radio Cabinet and chassis might help us zero-in on your model or something close??

Here’s a link to lots of pics of the S-22. I have seen a pic of the S-42 that Dan mentioned with two different tube line-ups, of which one was the same as S-22 mentioned above.

Thanks for all the info so far…this one is tough to find I think…here are some images of the radio cabinet…
It seems to have only one 247 output tube so not push pull…

Have a look for info on an RCA model R-7
Tube lineup looks good

It is close I would assume but the output stage on the S-25 is only single ended since there is only one of the 247 tubes…but close enough I guess for a starting point.
This era of radio is always hard to find info on…drives me crazy.

Did you look at the R-6 ? http://pacifictv.ca/schematics/rcar6sch.pdf
It is single ended. I think that I missed that note on your radio.
There is some info on the web that RCA radios and GE radios are the same for some units.
Good luck with the radio.October 7, 2022 at 6:58 am #19033
Hey John, I think you are correct on the R6 model by RCA. Both G E and RCA had a close relartionship in those days. But they were not married. Up until 1929 RCA was only involved in the marketing of radios. It was not until shortly after 1929 that they got into building Radios. However, the tight relationship with G E continued with the sharing of models and designs, under different Model numbers. RCA had the same relationship with Canadian Westinghouse, I just looked at the picture of the cabinet for Peter’s radio and that of the R-6, and it too is quite similar in looks. You may be on to something here.
