I am looking for any and all information on the RCA Radiola 20. If you have any information available, it will be much appreciated.

I have a copy to Beitman's Most Often Needed 1926-1938
Radio Diagrams.

It has schematics for Radiola 16, 17, 18, 47, 48, 60,
80, 82, and 86 but not the 20. Let me know if one of
these is close enough to help (18 might be)
