Rauland PA Model 1960 preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

A multi-input tube public-address amplifier from Rauland-Borg, not a guitar amp. Four 6SQ7 mic preamps and a phono preamp are mixed through 6SC7s, then 6SN7GTA inverter and driver stages drive a pair of 6L6s through an interstage transformer. It is a heavy-duty commercial PA with separate high- and low-voltage supplies.
