EP4 Echoplex compressor
« on: October 25, 2024, 04:22:24 pm »
Wrenching on somebody’s EP4, and it has the compressor card. But get this… just 2 transistors, a couple of the oldest 1n4001 diodes I’ve ever seen, and no 3080 or any opamp to speak of.


Early variant?? Ever seen a two bean comp with full wave recto for CV?


I didn’t trace it…. Yet


But, just never seen one!


Thank,
Joe
