There are schematics for B3 and B4. Might be similar?

In 1929 there wasn't a lot of different tubes being used. You should have an 80 for rectifier. If there are 5 pin tubes with top connections they would be 24's. No top connections 27's. Most output tubes were 4 pin. In 1929 companies used 45's. Before that time 71A.

:Anyone know what tubes are in a Sterling Model B2-60 (1929 Imperial) console radio?
