Supro 1600 preset

Close · 74/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Supro 1600 uses Valco's 510-1 chassis. A 6J7 pentode input stage feeds a volume control and a 6SC7, which works as the second stage and phase inverter. That drives a push-pull pair of 6V6GTs into a field-coil speaker, on a 5Y3GT rectifier.

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.
