Fixed a toasted channel in one of these brutes, DC offset and bias are both rock solid. Unit kicks protection after warming up? Can't figure out what's triggering it?? I recapped and tested transistors on protection board as well. Anyone know more about these amps then myself??
I'm thinking out loud here, but the unit has some thermo-sensors attached to the output heatsink. Do these ever go bad or would they just be either open or closed??
