Gibson GA-30RVT Invader - Channel I preset

Verified · 91/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The GA-30RVT Invader is Gibson's 1960s two-channel combo with reverb and tremolo. Each channel has its own Loudness, Bass, Mid and Treble on 6EU7 stages. Spring reverb and an optical (LDR) tremolo with depth and frequency are footswitchable. A 12AU7 long-tail inverter drives a pair of 7591s from a silicon-diode supply with an OA2 regulator, into a 10-inch and a 12-inch speaker, for a firmer, more hi-fi clean than the 6V6 GA-30s.
