Dynacord LE 120 preset

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

The Dynacord LE 120 of 1958 is a German valve power amplifier with no preamp channels. One ECC83 provides an input gain stage and a phase inverter driving a push-pull pair of large EL156 output pentodes on fixed bias, with separate bias adjustments for each valve (the I and II points). An EM71 magic-eye indicator shows output level, and the transformer has 8 and 16 ohm taps. The EL156s give it big, clean headroom for PA or instrument rigs.

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.
