Re: 1 strand of corona?/Class Demo

The question was asked "where is the strand of carona you are talking
about?" If it is near the top of your secondary you may have your primary
tuned slightly above the secondary frequency. Moving youre primary tap
slightly more turn length should move the carona to the top of your coil. If
the hot spot is in the center double your primary length. You could also
have a bad coating point on your coil that neads a clear finger nail polish
touch up. Your request dosent provide enough information to help you well.
