Supro Statesman S6699 - Channel 2 preset

Verified · 87/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Supro Statesman S6699 is a large two-channel Valco amp. Each channel has high and low inputs, a bright switch, its own volume and its own bass and treble; one channel also carries a spring reverb driven by a 6973 power pentode, with an intensity control and footswitch. A 12AX7 tremolo with speed and intensity is footswitchable. Four 6L6s run as two push-pull pairs, each with its own output transformer, on a diode bridge rectifier with a standby switch.
