Davoli Show 5 Preamp preset

Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Davoli (Krundaal) Show 5 is a 1968 all-transistor guitar preamp built to drive a separate 60-watt Davoli power unit. Normal and Effects inputs feed the same BC109 preamp with bass and treble controls and an output level; the Effects path adds a transistor-driven spring reverb with its own level and a socket for the Autotone accessory, plus a footswitch jack. There are no valves and no power stage on the drawing.
