Sound City PA200R preset

Verified · 82/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Sound City PA200R is a hybrid PA head with reverb, rated at 200 watts, made by Dallas Music Industries. Six identical transistor input boards each carry their own volume, treble, bass and reverb-send controls. A transistor reverb driver and recovery stage has a master reverb volume, and a master volume feeds a transistor driver with an interstage transformer that drives four fixed-bias KT88s. Outputs cover 4, 8 and 16 ohms plus a 100 V line tap. Built for band PA: loud and clean, with solid-state inputs and a valve output section.

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.
