Valco Airline 62-9052 - Channel One preset

Verified · 82/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Valco-built Airline 62-9052 was sold through Montgomery Ward's Airline brand, one of several OEM arrangements through which Valco distributed its amplifier designs to major catalog retailers. The circuit is shared with contemporaneous Supro and National models, delivering the characteristic Valco brightness and raw American character under the Airline name. Airline amps have become collectible partly due to their Jack White associations.
