Was the original final transistor heat sink only anchored
to the transistor case by a pressure fit?
Did you try to firmly anchor the original heat sink with
some type of insulated mounting hardware?

You'd
Well, yes and no... you are right to think along
the lines of the isolated or emitter-case (the
emitter lead grounded) transistor being a better
solution.
One could use a Delrin, Teflon, G4 or G10 material
to firmly secure the original heat sink. The added
capacitance should be minimal if

Also note the original transistor had more output,
so one would have to also take that into consideration
No, it would drop off to just under a watt after 10 min. The replacement does
2.3 watts after 1 one hour, so it's got more output as far
