The channel I fixed was fine, but the other channel blew some outputs. So, I again bought entirely new outputs transistors for the channel and replaced the drivers as well. Checked it over thoroughly and figured it was just because I had mixed some of the “good” transistors left over from each channel previously to fix the 2nd channel, but they may have been unknowningly damaged. Then I had another problem which I finally just solved! After I repaired ch 2, when I tested the amp, the protection light would not come on when I turned it on and the relay would never click on the channel…. so after countless hours of searching components and tracking down the source of the problem, I noticed a small crack on the edge of the volume control board which happened to run through the leads of a couple components, and with the ohmmeter saw that t
