Gibson GA-2RVT - Normal preset

Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The GA-2RVT is a two-channel 1960s Gibson combo, two inputs per channel, each channel with its own volume. Four 6EU7 tubes handle the preamps, tone circuit, spring-reverb recovery and the tremolo oscillator (depth and frequency controls); a 12AU7 drives the reverb tank and splits phase for a push-pull pair of 6V6GT tubes on a 5Y3GT rectifier. Reverb has an on/off switch. Its circuit is very close to the GA-25RVT.
