My lead III will run for about 3 minutes then turn off. I'm not sure what's wrong, but wanted to try to repair it myself. Does anyone have any suggestions or a schematic.

The thermal breaker is a bolted down black button with two white with a black stripe wires on it.
It's mount in the middle of the heat sink that the output Transistors are on.
If you turn the amp on and blow on it with a hair dryer I bet the amp will shut right down!
If that's the case you can just jump it out for now and use the amp , just first check that the amp is indeed not running hot which would indicate a bias problem.
