Let’s Get Started
The preamp is an exacting replica of the EP-3 preamp, from the 22v power supply, to
the JFET preamp, to the circuit loading contributed by the echo function (we made a
filtering circuit that mimics the loading), to the mixer output circuit. The buffer also runs
off of 22v and is a discrete silicon transistor based buffer.
Honing down on this circuit was critical and a long journey. We dedicated hours and
days into this design, revising our prototype until all agreed that what we had concocted
was sonically perfect!
