Stromberg-Carlson ASE-8 / ASP-80 preset

Verified · 82/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

A Stromberg-Carlson stereo hi-fi pair: the ASE-8 dual-channel preamplifier and the ASP-80 dual-channel power amplifier. ECC83/7025 stages handle the phono input and tone controls. In the power amp, a 7199 voltage amp and phase splitter on each side drives a push-pull pair of 7355s. As a valve hi-fi rig it sounds clean, full and wide, built for fidelity rather than grit.

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.
