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

The PA-100XR is a tube amp from the Oliver Sound Company of Westbury, New York, a version of the PA-100X with reverb and tremolo added. Channel 1 has volume, bass and treble controls. Channel 2 adds a mid control and an ultra-high switch. Both use 6EU7 preamp tubes and feed a 6AN8 inverter and a pair of 7027As with a 5AR4 rectifier. A 6EU7/6DR7 circuit provides the reverb and tremolo.

Schematic-derived preset files for the Neural DSP Quad Cortex and 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.
