Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The YGA-1 Signature is Traynor's guitar head of 1965–69, rated at 45 watts into 8 ohms. Two channels, each with two inputs, a 12AX7A stage and its own volume, mix into a second 12AX7A and shared treble and bass controls. A 12AX7A tremolo oscillator with speed and intensity modulates the bias of the output valves. A 12AX7A long-tail inverter with speaker feedback drives a pair of 7027As from a silicon bridge rectifier with a choke and standby switch.
