I, among many others here, resoldered the amp in my 90 300TE and it came back to life for a couple weeks before going belly up again.

Does the board put out too much heat to prevent using silicon to fill half the housing to eliminate vibration like BMW does on the relays on my 86 K75 motorcycle?

Granted it would mean the board couldn't be removed again, but if it keeps the joints from cracking, who needs to remove it? Then again, I don't want to start a fire either...
