Dynacord Dynaphon MV 1 preset

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

The MV 1 is an early amplifier sold under the Dynaphon name by Pinternagel, the company that became Dynacord. Two EF40 pentodes handle the microphone and radio/pickup inputs, an ECC40 serves as driver and phase splitter, and a push-pull pair of EL12s on an EZ12 rectifier delivers 15 or 30 W with a 200-ohm line output, making it a period PA/instrument amp rather than a dedicated guitar design.

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.
