Vox AC10 Super Reverb Twin preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The AC10 SRT (Super Reverb Twin) is a small JMI-era Vox combo that adds spring reverb and vibrato to the AC10 format. Two inputs feed an ECC83 stage with Volume and Tone; the other half of the ECC83 is the vibrato oscillator, with Speed, Depth and a footswitch. An ECC82 drives the reverb pan and a second ECC82 recovers and mixes it under a Reverb control, then an ECC82 phase inverter feeds two cathode-biased EL84s on an EZ81 rectifier.
