I have several of these sets and never had that problem.
One did have a 2SC41 that got quite hot but changing the transistor cured it,normally they run warm to the touch but no more.
It could well be the 1DK1 eht rectifiers loading down the output stage.Try disconnecting them and see if the 2SC41 temp drops and the waveform improves.
You could think about solid state replacements for them.
Is the HV solid state diode ok on the board just along from the transformer? I had a problem with one..Again, disconnect one end and see if 2SC41 heat reduces.
Good Luck.Not the easiest sets to work on.
