Dynacord Imperator preset

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

The Imperator is a 1970 hybrid Dynacord amp. A BC147 transistor preamp has bass, low-noise and guitar inputs plus organ and rhythm-instrument inputs, bass and treble boost switches and active bass and treble controls. A valve power board then uses one ECC81 as voltage amplifier and phase inverter to drive two fixed-bias EL34s into 4, 8 or 16 ohms, on a silicon-rectified supply of about 740 V with a standby switch.

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.
