So.... Out if curiosity. Does series/parallel inductance apply to the secondary coil? Pretty much, what if I used a larger gauge wire on the bottom third of the secondary and the top two-thirds use a smaller gauge of wire? What about a secondary with 2 coils in parallel? Would parallel even be possible? _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
