Looking at the Power transistors a little more closely, I think I substituted the TIP147 and TIP142 for a TIP147T and TIP142T, which look smaller, have a different hfe (gain?. I wonder then, if that's why R66 popped. Should I get some transistors without the T suffix?
The originals did check out with the diode tester on my multimeter though. Weird.
