Davoli Tempest 50 preset

Close · 70/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Davoli (Krundaal) Tempest 50 of 1972 is a single-channel all-transistor preamp on three BC109C stages. Two inputs feed a Sensitivity control, then bass, middle and treble, a three-position Super Treble switch and a master Volume. There is no presence control and no power stage: the output goes through a nine-pin socket to a separate Davoli U.P. 40 power unit.
