Hello everybody. I have this antique tube radio. Tubes are 35 27 24 35 27 47 47 80.
I found this R9A model was done by Marconi co. (on another site)... Anyway this seems to be the same as the R7A or R7, R9 by RCA. Does anyone know anything about it? I am trying to track down a correct scheme.

... Correctly it seems to be the same as R7A not R7 or R9 ... anyway I think there must be some differences between the R7A and the R9A. Can you help?

Thanks

Hi

Technical information on RCA R7A can be found here:

It's a 1931 radio.
