Original poster: "Terry Fritz" <twftesla-at-uswest-dot-net> Hi All, If you ever wanted to become an electrical engineer in an afternoon, you should check this site I found. It has a ton of great electrical engineering information in a small space, much of which applies directly to coiling matters. http://www.tpub-dot-com/neets/ The real degree will take longer ;-)) Cheers, Terry
