    Hi Des,
    Are you going to share your designs with us.
    I have been researching how to make an EDM for more years than i care to mention. There are a couple of books written for the Amature EDM builder (sorry cant remember them off hand) but the electronics in them is very aged now and some parts are obselete. Im very interested in how you built your amplifier/spark generator. Would certainly love to see more.

    MeJasonT,
    sorry, I thought I had replied.
    the circuit is based on the Ben Fleming book found in archive.net, and I then added some limit switching/indication on the ram, and used flash capacitors from disposable cameras for the capacitors. All of the components are easy enough to find online.
    if more detailed circuit modifications are needed, I will need to draw them up before I can post them.
