Original poster: "cougercat by way of Terry Fritz <twftesla-at-uswest-dot-net>" <felix1063-at-home-dot-com> Hello All, I am thinking about building a TC and would like to know if LITZ wire were used for the secondary, would overall performance improve? Also - has anybody tried to use a TC to power an x-ray tube and if so - I'd like to know the gory details. Thanks --jeff
