I am looking for a schematic for Philco 46-350 code=125.
I have a version for code 121. One obvious difference if the audio output tube 3LF4 versus 3Q5GT.

Hi

Shouldn't be any difference with a radio using 3Q5GT vs. 3LF4. Both are electrically the same. Only base type is different. Should be able to use the same schematic with different tube pin numbers. Basing can be found here:
