Airline 7214 preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The 7214 is a small Valco-built Airline combo sold through Montgomery Ward. A single input feeds two cascaded 12AX7 stages with one 500K Volume between them (no tone control), then a cathode-biased single-ended 6V6 into an 8-inch speaker, with a 5Y3 rectifier and no negative feedback. That simple class-A setup breaks up early and sounds raw and compressed, typical of Valco's budget amps.

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.
