I had a few responses on this RCA set that was dead, and thanks to all who replied. TP15 was good, as well as the main filter cap. The problem was an open resistor RP81 - 22kohm, 1/2watt. This resistor supplies base voltage to TP15. Replaced it and the set is back to life and operating normally. I did leave the legs long on it to help dissipate heat. Thanks again to all who replied.
