I have a Philco Transitone 51-532 on my bench. I've replaced all capacitors and several resistors. It is a run of the mill 5 tube set with an oddball mix of tube formats (LOCTALS, minis). The schematic is on Ryder's 21-46. When I bring it up, it plays nicely (clear signal and good volume) for about 30 seconds, then a quick *pop* followed by silence. What is my best practice for troubleshooting at this point? It sounds like a resistor, but which one and at which stage?
