Fender Deluxe Reverb AB868 - Normal preset

Verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The AB868 is the early silverface Deluxe Reverb from the late 1960s. It keeps the blackface layout of Normal and Vibrato channels, spring reverb and vibrato, with a 12AT7 long-tail phase inverter driving a pair of 6V6GTs on a 5U4GB rectifier for about 22 watts. Early silverface Deluxes like this sound very close to the blackface originals.
