AX84 5W SE Poweramp preset

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

The power section of AX84's single-ended 5-watt DIY amp project, drawn in 2001: one 6V6S running class A with cathode bias and an adjustable trim, into a single-ended output transformer with 4, 8 and 16 ohm jacks or a rotary impedance switch. A two-diode solid-state rectifier feeds a five-stage RC filter, with an optional choke version, and a standby switch. Sheet 2 holds construction details rather than the input stage. It is a common first build for hobbyists.

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.
