Davoli 1080 Power Unit (1966) preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Krundaal (Davoli) 1080 is a 1966 stand-alone valve power unit with no preamp, built to be driven by one of Davoli's separate preamp modules. A pair of ECC82s provide a gain stage with negative feedback from the output transformer and a phase splitter, driving two fixed-bias EL34s in push-pull into a multi-tap output transformer. The high voltage comes from a silicon-diode doubler, with zener-regulated adjustable bias.
