Airline GVC-9064A preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Airline GVC-9064A is a single-channel Montgomery Ward tube amp with a 15-inch speaker. Three instrument inputs feed a 12AX7 gain stage, then Volume, Treble and Bass controls and a second 12AX7 whose halves provide another gain stage and a floating paraphase inverter. A push-pull pair of 6L6s on a shared cathode resistor runs off a solid-state bridge rectifier, with a line-reverse switch. There is no tremolo or reverb on the drawing.
