Rauland PA Model 1932 preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Rauland 1932 is a 1951 tube public-address amplifier, not a guitar amp. Three identical 6SQ7 microphone preamps, each with its own volume, feed two 6SC7 mixer stages, one of which also serves the phono input, then a third 6SC7 works as audio amp and phase inverter for a push-pull pair of 6L6Gs. Power comes from a 5U4G main rectifier plus a 6X5. Octal PA chassis like this are popular guitar-conversion projects.

Schematic-derived preset files for 16 Fractal and Line 6 modelers: Axe-Fx II/XL/XL+, Axe-Fx III, FM3, FM9, and the full Helix family (Floor, LT, Rack, HX Stomp, HX Stomp XL, Native).

Gridleak extracts amp parameters from original circuit schematics using AI vision — component values, gain staging, tone stack topology, tube types — then generates native preset files for every supported modeler. Every extraction is scored 0–100 and the score is published.
