Vox Berkeley II Super Reverb V8 preset

Verified · 91/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Berkeley II Super Reverb V-8 is the valve version of the American-market Vox Berkeley. Three inputs feed a 12AX7 stage with Treble, Bass and Volume, then a second 12AX7 stage. A 12AU7 drives the reverb line and a 12AX7 recovers it under a Reverb control, while a 12AX7 oscillator gives tremolo with Speed and Depth, both footswitchable. A 12AX7 long-tailed pair drives two cathode-biased EL84s into two 10-inch speakers, on an EZ81 rectifier.
