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

This schematic documents a modified Princeton Reverb AA1164 with the reverb and tremolo circuits deleted, producing a simplified version of the classic 12W blackface single-channel 6V6 combo. Stripping the modulation and reverb circuits leaves the core preamp and power amp topology intact, revealing the fundamental clean voice of the Princeton circuit. Custom modifications of this type were common among players seeking maximum simplicity.
