Fender Vibrasonic 5G13 - Vibrato preset

Verified · 94/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Vibrasonic 5G13 is the first of Fender's brown-Tolex amps and the first to ship with a JBL 15-inch speaker. Its two channels each have two inputs and their own volume, treble and bass, with a shared presence control and harmonic vibrato with speed, intensity and a footpedal jack. Five 7025s run the preamp, vibrato and phase inverter, driving two 6L6GCs on a solid-state rectifier.
