Airline GIM-9111A preset

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

The Airline GIM-9111A is a single-channel Montgomery Ward tube amp sold with a 15-inch speaker cabinet. Three inputs feed a 12AX7 gain stage, then Volume, Treble and Bass controls and a second 12AX7 that provides another gain stage and the phase inverter. A push-pull pair of cathode-biased 6L6s runs off a solid-state bridge rectifier. The Bright switch on the panel only dims the pilot lamps; there is also a line-reverse switch.
