Epiphone EA-5RVT Emperor - Channel 1 preset

Verified · 83/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The EA-5RVT Emperor is a 1960s Epiphone tube combo with two channels, each with two inputs and its own volume and tone controls, plus spring reverb and an optical (lamp and LDR) tremolo. 6EU7 twin triodes handle the preamp and tremolo, a 12AU7 drives the reverb, and a 7199 pentode-triode serves as the phase inverter. A fixed-bias pair of 7591 output tubes on about 420 V is fed by a GZ34 rectifier, with standby and polarity switches and a monitor jack.
