Fender PA-135 - Channel 3 preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Fender PA-135 is a tube-powered public address head delivering 135W through four 6L6 tubes, designed for vocal and instrument amplification in a PA context. Four independent channels with individual tone controls made it useful in band rehearsal and small venue settings. While not a guitar amplifier per se, its all-tube construction and 6L6 output stage gave it a warm, musical character.
