I have my AMP9, build#2 with paralleled outputs. While hooking up the outputs, I missed my screw terminal on chanel 2 and had the (-) wire under the board, touching the output capacitors on the bottom. I did not see this, until I turned it on. Uh, no sound can out from those 2 channels. Since I had ch1 and ch2 paralleled, the output from ch1 would have reached the capacitor under the board. I hear nothing from these channels, unless the pot is at full volume, then I just barely hear the sound. Ch3 and Ch4 work fine.
Question, what did I likely fry, the caps, the chip, other? Any suggestions for repairing this? Or do I now own a 2 channel amp9?
