Traynor Mono Block II preset

Verified · 89/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Mono Block II is a 1976 solid-state Traynor amplifier rated at 325 watts into a 2-ohm minimum load. High and low inputs feed a discrete transistor preamp with volume, bass and treble controls, then a five-band slider graphic EQ (50 Hz to 2.5 kHz) plus a rotary middle control and a master volume, with preamp-out and power-amp-in jacks. The power amp is a quasi-complementary transistor stage with paralleled output devices on ±56 V rails.

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.
