Hello. I have 2 of these radios and cannot find the proper schematic for them. They use the 35L6GT output tube and have a 1K ohm resistor in the heater circuit between the 7A8 and 12AV6. Many resistors also vary from the schematics I’ve found on Nostalgia Air, et al. What’s worse, one of them I can get to work, but the other seems to have a major problem somewhere in the power circuit. It appears that the latter was ‘repaired’ using the schematics in Riders 23. Copuld someone point me to or provide the correct schematic? Thanks for any help!!

: Correction to below...I meant 12BA6 instead of 12 AV6.

Nostalgia Air sometimes will not have all the Production Change Notes for a model past the initial model (Code 121). Try asking on The Antique Radio Forum http://www.antiqueradios.com then.

Hi

Philco used different tubes but circuit should be the same. When they used lower filament voltage tubes a reasistor was added in series with filaments. Shouldn't be 1K.. Would expect resistance to be less than 100 ohms.

Where did you find differences? Noticed you mentioned 12AV6. This tube is similar to 14B6 and 7C6 in loctal. 12BA6 is similar to 14A7 and 7B7 loctal.
