Newcomb Model 10 preset

verified · 82/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Newcomb Model 10 is a tube school and phonograph amplifier rather than a guitar amp. Mike, magnetic (high/low), crystal, radio and tape inputs share a 6SC7 preamp with a six-position record-equalisation selector (Foreign 78, London, Columbia, NAB-RCA, AES, Domestic 78), then one volume plus bass and treble controls. A 12AX7 provides gain and phase inversion for a push-pull pair of 6V6GTs on a 6AX5 rectifier, with 8 and 16 ohm outputs.

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.
