Airline GVC-9056A - Channel 1 preset

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

The Airline GVC-9056A is a two-channel Montgomery Ward tube amplifier. Channel 1 has three inputs and Channel 2 one, both labelled for microphones, and each channel has a 12AX7 gain stage with its own Volume, Treble and Bass and a recovery stage. A 12AX7 long-tail inverter with negative feedback drives two cathode-biased 6L6s off a solid-state rectifier, into an assembly of four 10-inch speakers and a horn. There is no reverb.
