Close · 65/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Airline GIM-9151A is a Japanese-manufactured mid-power Airline combo from the early 1970s, featuring a hybrid circuit with solid-state preamp and tube power amp section using EL84 output tubes. The design reflects cost-conscious engineering aimed at the student and beginner market after Valco's collapse. Tonally it sits between budget and workmanlike, with a firm clean sound and modest but usable harmonic saturation when overdriven. Its EL84 power section gives it a slightly British character compared to the earlier 6V6 and 6L6 Valco models.

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.
