Good point Pleat!
Yes, if that two lead diode in that clip next to the thermal breaker in out of its clip , or not held tight in its clip then the amp can run hot and shut down.

Be careful when moving that diode, as it's leads are fragile, and also make sure that it's leads are not touching the clip.
If your thermal breaker is ok and the bias diode is held in the clip well then the amp should be able to sit on and just idle for hours with the rear of the chassis only feeling warm to the touch, not hot!
