i often help a guy fixing amps - dont get them myself.

the most common cause of final destruction is faulty bits in the pre-drive either overdriving the finals or turning both parts of a push/pull pair on together or overlapped!

it can be anything - last one was just an out-of-value resistor shifting the bias enough to make one transistor drive against the other!!!
