    Does anyone have a schematic for a reissue EHX Polychorus? I accidentally let the magic smoke out of mine and need to replace a couple of parts. I can find vintage schematics, just not modern ones, and I need modern.

    I don't think the schematic for the reissue is available... at least I've never seen it.

    Is there is something in particular you're looking for on the board itself? I own both a reissue and original version and don't mind checking it out..

    Ooh, thanks! There's a big cap near where the power comes in that I think is part of the power circuit. Right next to it is a resistor and what looks to be a diode, in series. Both the resistor and the diode are smoked. (when I bought it, it came with the EHX 40v power supply, not the 24v. It was subject to some real abuse! I figured this out when debugging...)

    If you could double-check to make sure it's a regular diode and not a zener, and get the value of that resistor, I'd really appreciate it. I can probably get photos if you need more details.
