Close · 60/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Randall RT2/50 is a tube power amplifier from Randall Amplifiers' hybrid series, designed to be paired with Randall's solid-state preamps. It uses a pair of 6L6 output tubes to deliver 50 watts of all-tube power, combining Randall's renowned solid-state preamp clarity with the dynamic response and harmonic richness of a tube output stage. This approach was widely adopted by high-gain players who wanted tight, focused distortion with tube feel.

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.
