Orange AD140TC - Clean preset

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

The AD140TC is a twin-channel all-valve Orange head from the AD series, built around 2001 when Trace Elliot engineered Orange's amps. The Clean and Dirty channels are completely separate: each has its own ECC83 gain stages, Gain, Treble, Middle and Bass controls, Master and even its own ECC83 long-tail-pair phase inverter. A footswitched relay picks which inverter drives the four fixed-bias EL34s, with 8 and 16 ohm outputs and a slave out.

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.
