Gibson GA-30RV - Channel 1 preset

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

The GA-30RV is a Gibson two-channel combo with reverb. Each channel has its own input pair and volume on a 6EU7 triode. There is one tone control, and a 6EU7 and 12AU7 drive and recover the spring reverb. A 12AU7 split-load phase inverter feeds a pair of 6V6GTs with a 5Y3GT rectifier. The 6V6s give it a warm, rounded American clean with a soft edge when pushed. It is a different amp from the non-reverb GA-30 and from the 7591-powered GA-30RVT.
