It's possible the wire I got has inferior insulation, it was all
purchased fro the same surplus dealer. The insulation is a clear
honey color and I've done a brekdown test on the #20 gauge wire and
it only tolerates about 150 volts. By contrast I have a spool of #26
formovar insulated wire that I tested and it held to just over 900
volts!

Why people care about the number turns is beyond me since a Tesla
coil dosen't operate on a turns ratio!
