Danelectro Centurion 275 - Channel 1 preset

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

The Danelectro Centurion 275 is a two-channel tube combo from Danelectro's Neptune City, New Jersey years. Each channel has its own volume, treble and bass, with normal and strong inputs; a 6CG7 drives and recovers a spring reverb, and a 6AU6 oscillator runs the vibrato with speed and strength controls and a dual footswitch. A 12AX7 phase inverter feeds a push-pull pair of 6V6GTs on a 6X4 rectifier, for a clean, bright tone that breaks up when pushed.
