Davoli 1080 Power Unit (1967) preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Davoli (Krundaal) 1080 is a 1967 stand-alone valve power unit with no preamp or tone controls, fed from a separate preamp module through a multi-pin input socket. One ECC82 serves as input stage and phase splitter, one ELL80 dual pentode drives the output, and a pair of EL34s run in push-pull with adjustable fixed bias into a multi-tap output transformer, with feedback from the speaker winding. Its UP80 designation puts it at about 80 watts.
