Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <Cydesho-at-aol-dot-com> I was running my coil today for a couple of minutes and after I was done, I went to pick up a extra toroid that was lying in the vicinity. I got a big static shock from it. I didn't think that tesla coils built up static charges because the operate on alternating current. Justin
