Magnatone 26R - Channel 1 preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Magnatone 26R is a mid-1960s Magnatone combo with spring reverb and the company's varistor pitch vibrato. Two channels, each with two inputs on a 12AX7 triode, their own Treble, Bass and Volume and a Bass/Normal/Treble switch, mix into a 12AX7 stage and two 6CG7 vibrato stages. A 6DR7 drives the reverb with a 6EU7 recovery, and a push-pull pair of 7868s from a solid-state supply drives the speaker.
