Verified · 91/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The AA763 Tremolux is an early blackface piggyback head with Normal and Vibrato channels and optical vibrato, but no reverb. A 12AT7 long-tail phase inverter drives two fixed-bias 6L6GCs on a GZ34 rectifier for about 35 watts of firm blackface clean tone.
