You pretty much covered it a lot better than I would have and brought back memories! I had totally forgotten about that transistor. I do remember a standard SK or ECG type sub would run hot (hotter than the original as that ran hot). Was there a capacitor that caused that transistor to run hotter than it did ordinarily???

I've got a ton of TX notes at my shop. I'll check tomorrow and paste what I have.

EDIT: found some notes on my old laptop (surprised it boots).

TX81 cycling: CP01 (100uf/35v) *very common*
Tp15 P/N RCA #198752 (the transistor that Zeno mentioned)
DP18 (use ECG580)

Dead or otherwise with intermittent issues:

Cp32 --202044
Tp10--198794
Rp41--198678
Cp06--198559
Cp08--190501
Tp06--198748
Fp01--198605.

There is more... these were very common and were made by the millions, which is why there is so many notes. Generally, the first three tips are the most common IIRC.
