Original poster: "by way of Terry Fritz <twftesla-at-uswest-dot-net>" <Fucian-at-aol-dot-com> Hi all and ryan, could it be possible that the seconday burned because its 1in thick?Wouldnt an inch cause the rf energy to be absorbed more in the secondary?I thought thinner was better because it absorbs less rf energy.Please correct me if im wrong cuz this has been eating me up. matt
