Watkins Dominator Bass Mk I - Bright preset

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

The Dominator Bass Mk I is the bass version of the Watkins Dominator and shares its circuit with the Dominator Mk III and Power Musette Mk II. Two channels each run an ECC83 gain stage into their own Treble and Bass controls, a second triode stage and their own Volume, with a Bright switch on one channel. An ECC83 long-tailed pair drives two EL84s for 15 watts into a 12-ohm output, from a BY127 silicon-diode rectifier.
