Fender Pro Amp 6G5 - Normal preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The 6G5 is the early-1960s brownface Pro Amp, a 1×15 combo with Normal and Vibrato channels, each with two inputs, Volume, Treble and Bass. The Vibrato channel runs through Fender's harmonic vibrato: 7025s generate the LFO and split the signal into high and low bands modulated against each other. A Presence control sits in the feedback loop, and a 7025 long-tail inverter drives two fixed-bias 6L6GCs on a silicon rectifier.
