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.
