Sano 50WRT preset

verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The 50WRT is a tube amp from Sano Corporation of New Jersey, built as a separate preamp and the 30W/50W power amplifier. Stereo (Cannon), Instrument and Guitar inputs each have a 500K level into 12AX7/12AU7 stages, then bass, treble and volume. A 6U10 compactron drives a Hammond 4C echo device, and a 12AX7 tremolo has frequency and gain. The power amp uses 12AU7 stages and inverter driving two cathode-biased 8417s from a 5U4 rectifier.

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.
