Work on the Philco 39-30 has begun
#23

The audio coupling cap is marked 35 on the schematic. It is a .01 uF tubular wax cap, connected from the triode plate of the 75 tube (Pin 2) to the control grid of the 41 output tube ( pin 4).

If this cap is leaky it could be causing your overheating problem, so definitely replace it.
