Rock-Ola 1442 Jukebox Amplifier preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The tube amplifier chassis from a Rock-Ola Model 1442 jukebox. Two 6SN7 dual triodes handle the preamp, tone and paraphase phase-inversion duties, driving a push-pull pair of 6L6s with a 5U4 rectifier. Like many jukebox amps, it has become a popular candidate for conversion into a guitar amplifier, with a stout 6L6 output stage and a big power transformer.

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.
