Many thanks to those who shared a schematic. My searches last night came up with what I thought was a schematic, but having it presented here confirms it. Now, if only the manual were written in English... Google translate isn't much help, and I'm curious about a couple of the switches.

As far as output transistors go and possible failures, it appears from the schematics and the circuit board diagram that the transformer labeled TP2 is the one that's getting hot to the touch. So, maybe transistors T11 and T12 could be suspect? Looks like they might can be removed from their sockets... And there's a solder joint on a resistor in the nearby vicinity that could be suspect... Hmmm... The plot thickens and the game's afoot!
