Harmony H-200 - Microphone preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The H-200 is an early postwar Harmony combo with two instrument inputs sharing one volume control and a separate microphone input with its own volume, plus a single tone control. A 6SN7GT twin triode amplifies both inputs, a 6SL7GT works as the paraphase phase inverter, and a push-pull pair of 6V6GTs runs from a 5Y3GT rectifier into an 8-inch field-coil speaker. Low-gain and clean until pushed hard.

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.
