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

The Thermion TN120 is a two-channel tube head from Ibanez's mid-2000s Thermion series. Vintage and Hot channels each have their own gain, bass, middle, treble and master, on a relay-switched front end with pad and bright switches and five 7025/12AX7 preamp tubes. A long-tailed-pair inverter drives four fixed-bias 6L6GCs with a 6L6GC/6550 bias selector, with presence, a dampening mode, an effects loop and a multi-tap output transformer.
