Does anyone know of an on-line schematic for a power supply that will handle
typical A, B & C voltages for a 1920's radio? ( for RCA AR-812)
I see an assembled unit on line that looks pretty nice but I wondered if I had
to spend the $149 or could I build one for lots less? The kit from AES doesn't
have the C supply, I'll need 3 to 3.3 volts for the filaments and I'd rather
not use batteries for a battery eliminator.
