Description

Exact EP-3 circuitry, from the 22 volt power rail, to the JFET preamp (later spec), to the mixer stage, to the high gain silicon transistor based record and playback amplifiers, to the feedback loop. All circuitry is faithfully reproduced and fine-tuned from the original EP-3 specifications. The only thing missing are the record and playback heads, with a 24-bit high-fidelity digital delay line taking the place of the tape.

All-discrete, through-hole construction with orange drop 225P capacitors, carbon composition resistors, germanium diodes, and other premium parts.
