Unknown All American Dual Lite - Fender preset

Verified · 93/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The All American Dual Lite is a DIY two-channel amp built around American circuits. A three-way switch picks one or both preamps: a 12AX7 Ampeg Gemini II-style channel with volume, an Ultra Hi switch, bass and treble, and a 12AX7 blackface-Fender-style channel with treble, bass, volume and a bright switch. A 12AT7 long-tail inverter with negative feedback drives two fixed-bias 6L6s with an adjustable bias supply, from a solid-state 5R4 replacement rectifier.
