Wurlitzer P38 Stereo preset

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

The Wurlitzer P38 Stereo is a German-built stereo tube amplifier for electric piano/keyboard use. Each of its two identical sides uses ECL86 triode-pentodes, the triode as input and the pentodes in push-pull, with shared bass and treble controls and a bridge-rectified supply.

• Made in: Germany
• Channels: 1

Schematic-derived preset files for the Neural DSP Quad Cortex and 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.
