Verified · 82/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

This is the Vox AC30 schematic from approximately 1989, during the early Korg ownership period when Vox amps were manufactured in the UK under closer supervision. The circuit closely mirrors the classic JMI-era AC30 topology with Normal and Top Boost channels, four EL84s in cathode bias, and the characteristic lack of negative feedback producing the amp's famous compression and bloom. Korg-era build quality improved significantly over the Dallas Arbiter years.
