Original poster: "by way of Terry Fritz <teslalist-at-qwest-dot-net>" <Pomnept-at-aol-dot-com> I just realized my primary and secondary are wound in opposite directions! This is my second coil and I didn't realize until it was too late. Is this a concern? My first coil was based on plans which indicated that they should be wound in the same direction. Panic! Robert H.
