Fender Super Reverb Ultralinear (1978-1981) - Normal preset

Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

This is the late silverface Super Reverb, the 70-watt RMS version of the late 1970s. Normal and Vibrato channels each have volume, treble, middle and bass with a bright switch. A master volume with a push-pull boost follows the mix, and the Vibrato channel adds 12AT7-driven spring reverb and 12AX7 optical vibrato. A 12AT7 long-tail inverter drives two 6L6GCs at about 500 volts on a silicon rectifier, making it louder and stiffer than earlier Super Reverbs.
