Silvertone 1301 preset

verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Silvertone 1301 (chassis 319.190) is a 1950 Sears practice amp and about as simple as a tube amp gets: two instrument inputs mixed into a 6SJ7 pentode gain stage, a single 500K volume control with the power switch on it, and one cathode-biased 6V6GT running single-ended into the speaker. No tone control. A 5Y3GT rectifier supplies the high voltage.

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.
