Peavey Classic 50/50 preset

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

The Peavey Classic 50/50 is a mid-1990s two-rack-space stereo tube power amp for rack guitar rigs, with no preamp of its own. Each 50-watt side has its own Level control, a 12AX7 input stage with feedback-based tone shaping, a 12AT7 phase inverter and four EL84s into its own output transformer with 4, 8 and 16 ohm taps. A relay links the two sides for mono use, and there are line outs and transformer-isolated direct outputs.
