Impact 60 Reverb Tremolo - Channel 2 preset

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

The Impact 60 Reverb Tremolo is a 60-watt amp from the English maker Impact, dated May 1968 on its factory drawing. Two channels each have two inputs, their own treble, bass and volume, and two ECC83 gain stages. ECC83 stages drive and recover a Hammond spring unit with a reverb level and footswitch, and an ECC83 oscillator drives a light-cell tremolo with depth and footswitch. An ECC83 long-tailed-pair inverter feeds two fixed-bias EL34s.
