Epiphone EA-65 preset

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

The EA-65 is a single-channel Epiphone tube combo with two inputs. A 6EU7 preamp has treble, bass and volume controls, and a lamp-and-LDR network driven from the speaker output acts as a factory-set limiter on the second stage. A second 6EU7 phase inverter drives a fixed-bias pair of 7591s on about 425 V, with a GZ34 rectifier and a standby switch.
