Fender PS-160 preset

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

The Fender PS-160 is a CBS-era valve PA head rated 160 watts RMS. Six identical 7025 input channels each have Volume, Treble, Bass and a reverb send, with an aux input/output and its own volume. A light-dependent-resistor compressor, a 12AT7-driven spring reverb with Dwell and Intensity, and a Master Volume with bass, mid and treble feedback switches lead to a 6V6GTA driving a transformer-coupled pair of selected 6550s, with a VU meter on the panel.
