A-Wai Dirty Greed - Lead preset

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

The Dirty Greed is a two-channel, roughly 20-watt all-valve head design from the small independent builder A-Wai. The clean channel is a single ECC83 stage with its own volume, while the dirty channel cascades three ECC83 stages under its own gain control. Relays select the channel, and a further gain stage and cathode follower drive the tone stack, then a long-tail phase inverter and a pair of 6V6s with adjustable fixed bias.
