Epiphone EA-300RVT Embassy - Normal preset

Verified · 89/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The EA-300RVT Embassy is the big Epiphone combo of the 1960s, with two 12-inch speakers and an external speaker jack. It has Normal and Reverb channels, each with its own volume, treble and bass and a bright switch, plus spring reverb and tremolo controlled from a foot pedal. A 12AU7 drives a push-pull driver transformer feeding four fixed-bias 6L6GCs into one output transformer. Power comes from a silicon diode rectifier with a filter choke and an 0A2 regulator.
