Davoli Tempest 60 preset

Close · 66/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Davoli (Krundaal) Tempest 60 guitar/bass preamp of 1975 is all-transistor. Two inputs each have their own volume and mix into a two-transistor gain stage with a Sustain switch, then shared active middle (700 Hz), presence (3 kHz), bass and treble controls and a master volume. A mixer output jack is provided, and the main output feeds a separate Davoli U.P. 1040 valve power unit through a nine-pin socket.
