TP15 was a goof by the guys who designed this set. Normal operating temp
of the original trans in these is around 85 deg C. At about 100 C most
transistors have reached the point of thermal runaway. The RCA
replacement in my opinion also runs too hot. Use something with a higher
current rating than original or install one of the small heat sinks made
for T16 case. This was just a case of trying to save too many pennies
when the set was built. Any NPN with proper voltage and about 1 amp I
rating will work, nothing fancy here just working at DC.
