Unknown Dual Lite (British) - Marshall 18W preset

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

The Dual Lite (British) is a DIY design that puts an AC15-style channel and an 18-watt-Marshall-style channel in one small EL84 amp, chosen by a switch at the input. One side is an EF86 pentode with its own volume and a six-position Brilliance switch; the other is a 12AX7 cascade with its own tone and volume. A 12AX7 long-tail inverter with a Cut control drives two cathode-biased EL84s with no negative feedback, from a 5Y3 rectifier.
