  • Gutshot of EHX Polyphase?

    A buddy brought one over for repair this week, along with a bunch of other vintage EHX pedals. The power supply appears to have suffered some kind of melt-down and everything in that corner of the board is charred beyond recognition. Given that the components don't have dental records, and I'm a little too pressed for time to do the detective work using the schematic. I'd rather just knoiw what goes where and do a quick replacement. I've been able to find pics online of the copper side but not the component side. I was hoping someone might be able to point me to a gutshot of the board on the component side.

    This is the non-reissue unit: 5-knobs, black and blue graphics, through-hole components, old folded-steel chassis.

    Still can't find a gutshot, so here's mine. Perhaps one of you fine folks might be able to tell me what goes where component #1 used to be, before things went up in a thermal mess, and what component #2 is.

      It's uh... well if I just TELL you, how will you ever learn anything? Kids these days...
      Education is what you're left with after you have forgotten what you have learned.

        It seems that this is part of the power supply - at the bottom of the schematic.

          Thanks to all. Someone sent me a gutshot of that corner of the board. It,s not the clearest i the world, but the colour stripes visible identify the missing components as resistors, and will allow me to narrow down what resistors they could be.
