That's a lot of damage to have not blown a 20 amp fuse. Would be interesting to pull that cover/heatsink and see what cooked. That's a lot of gunk to have come from even a couple of electrolytic capacitors. Then again, less than 240 watts wouldn't have blown that fuse (12v x 20amps). Nobody could have bypassed that fuse? Have had three Bose amps fail but they have all lost their "proprietary" IC as their failure mode.
