Sound City 200W LE - Normal preset

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

The Sound City 200 LE is a 200-watt British valve head built by Dallas Arbiter. Brilliant and Normal channels each have two inputs, an ECC83 half and their own volume, then another ECC83 stage feeds a Treble/Bass/Middle stack with factory presets and a Presence control. An ECC81 long-tail phase inverter with loop feedback drives four KT88s in fixed bias, fed by twin silicon bridges and a choke, with 4/8/16-ohm and 100 V line outputs.

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.
