Rickstone Powersupply H30 preset

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

The Rickstone Powersupply H30 documents the power supply circuit for the H30 power amplifier, providing technical reference for the rectification and high-voltage filtering design used in this British 1960s design. Power supply documentation is essential for successful restoration of vintage tube amplifiers, where capacitor failure and voltage drift are common age-related issues. This schematic is an important preservation document for Rickstone H30 restorers.

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.
