Ok, didn't manage to get the board out. This is a nicely built unit, I like the method of thermal contact, and the aluminum body is very thick. I bet these things last a long time if you don't try prying them apart :)
General view of the damage so far:
The nut on the center stud was loctite'd. Nut came off, but the stud is solidly adhered to the board. After more probing, I think the first place the trigger voltage goes is this resistor leg, rather than that transistor. Current plan is to add a wire to that resistor leg, put the amp half way back together, and test it in the car to see if I get 12v when I want it, and that the amp behaves normally. Perhaps tomorrow.
