Hi all,

I'm restoring a Philco 48-1263 radio/phono. I had no tone variance coming from the on-off/tone potentiometer and on closer looking found one end of the pot dead ended on a terminal strip. It seems a cap and resistor were flat out missing. I replaced the cap from the pot wire at the terminal strip to the #2 pin, the plate, on the 7C6 AF Amp tube. Now I have bass, but only crammed into a very short end of the tone range. 90% of the tone range is full treble, no variance.

Did I maybe wire this wrong? I have the schematic, but I'm not terribly proficient reading them.

Thanks,
Alan
