I lost this once, and I’m not sure how. Thanks (again) to oldfrets.com, I saved it again and am posting it here for posterity. The last time I wanted to have my amp cleaned up, the repair guy was too nervous to take it. He was talking me OUT of it which is never a good sign when handing over prized gear. In theory, my little 6150T has the same schematic as the G6161. Today I plugged in and tried to flip on the tremolo and it decided to give up. Time for a repair.
