Alamo Fury 2566 preset

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

The Alamo Fury 2566 is a hybrid combo from Alamo Electronics of San Antonio, Texas. Two inputs feed a 2N5210 transistor stage, Bass and Treble controls, Volume and a second 2N5210 stage, which drive a 12AX7 cathode-coupled phase inverter and a push-pull pair of cathode-biased 7868 power valves into a 15-inch speaker, rated about 18 watts on the drawing. It is a budget design pairing solid-state gain with a valve output stage.

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.
