Vox AC10 (JMI) preset

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

The JMI AC10 is the small 1x10 Vox combo that sat between the AC4 and the AC15. Its Tremolo channel runs an EF86 pentode preamp with its own volume, while the Normal channel uses a triode stage with its own volume; an ECF82 drives the tremolo, with Speed and Amplitude controls and an on/off footswitch. One Tone cut control feeds an ECC83 phase inverter and two cathode-biased EL84s with no negative feedback, on an EZ81 rectifier.
