The Tremolux AA763 is the early blackface Tremolux from 1963, marking the circuit's transition from brown-panel cosmetics and tone to the cleaner, more refined black-panel sound. It delivers approximately 30 watts from two 6L6GC output tubes — a significant power increase over the 6V6-equipped brown-panel models — into a 1×12" or external speaker cabinet as a piggyback configuration. The AA763 revision introduced the classic blackface tone stack and longer-tailed pair phase inverter, giving it a cleaner, more articulate response with a smooth vibrato channel.
