Epiphone EA-500T - Channel I preset

Verified · 82/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Epiphone EA-500T was a larger tube amplifier from Epiphone's EA series, positioned toward the professional end of the brand's 1960s amplifier range. Its tremolo circuit was a notable feature at the wattage level, providing a warm, pulsing modulation effect well-suited to the surf and country styles that were commercially dominant during the mid-1960s. The EA-500T's tube circuit delivered substantial clean headroom, making it capable of cutting through in live performance contexts without unwanted breakup. It was a credible professional tool from a brand more often associated with student-level gear.
