Hi
According to Philco's service information, the added 1200 ohm resistor is rated at 1/2 watt. This version, as you know, does not use an electrodynamic speaker; it uses a PM speaker and two resistors in place of the original field coil.
It sounds to me like you have something in the B+ line drawing way too much current and burning up that 1200 ohm resistor.
I suggest you contact Chuck and obtain the full service information for this set, which includes all of the production change info including Code 128.

Well worth the nominal cost.
