I have to give you 11 out of 10 for patience and determination lol. I don't know if the hot transistor is part of the oscillator or a power regulator. If its a regulator i would check it's input voltage and any electrolitics across it's output. If it's part of the oscillator the caps could be breaking down, the peak to peak voltage can be more than you might expect. All very obvious to you i'm sure. Connect a volt meter to the supply that feeds that oscillator, just in case it's being silly :-D Electronics has a habit of doing unexpected things, then behaving itself just to annoy us lol.
You're not wrong - it pushes at least 100V p2p. There's a couple of ceramic caps rated at 500V near the bias trim pots! Worth being aware whats going on. I'm not sure if I am especially patient, but I do have a good supply of thinking juice...
