Verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

A Sano tube amp with two channels and four inputs: two Instrument inputs on channel 1, Accordion and Guitar on channel 2, each channel with its own 12AX7 triode and volume. A third 12AX7 triode feeds a bass/treble stack, then a 12AU7 gain stage with speaker feedback and a cathodyne inverter drive a cathode-biased push-pull pair of 7591s from a 5U4GB rectifier. The fourth triode is a tremolo with speed control and footswitch.
