i have this amp blown outputs and a blown K 408 A1266 small transistor. its board designation is QM1 how would this blow and what else am i going to have to look at?
That's part of the muting circuit. If I'm not mistaken, the center leg goes to DM1/2 (or QA1, QB1) near the preamp end of the board. You should check the muting transistors. I think they should be QA1 and QB1 but I'm not sure.
