This document covers a range of classic McIntosh Laboratory tube amplifiers including the MC-30, MC-60, MC-175, MC-225, MC-275, and MC2100, spanning the golden era of American hi-fi. McIntosh, founded in 1949 in Binghamton, New York, built these amplifiers to audiophile standards with their signature Unity Coupled Circuit transformers and green-glowing wattmeters. These models collectively represent some of the most celebrated tube audio amplifiers ever produced.

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.
