Rickstone Powersupply H40 preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Rickstone Powersupply H40 documents the power supply circuit for the H40, the highest-output model in the Rickstone H-series range. A 40-watt amplifier requires a more robust power supply than the 30-watt models, and this schematic captures the specific transformer, rectification, and filtering design Rickstone used at this power level. It is an important document for the rare owners and restorers of Rickstone H40 amplifiers.

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.
