Philco squeals on weak stations

There could be a cap somewhere that is supposed to shunt that crap to ground at a certain point, that is either open, not connected to ground, etc. Also second the lead dress theory.

I just repaired a 1936 Emerson with the same problem.

Though its a long shot, I found it was the 6A7 tube. It tested good but in the circuit it didn't work. You might want to check your 6A7 or 78's.

Good luck.
