Thanks to all who provided guidance with this problem. I built a second 
toroid with a major dia. of 13.5" and a 4" chord. I no longer have any 
corona build up or arcing from the top of the secondary. My TC now produces 
a very nice single streamer from the toroid and appears to be operating 
properly. I ran it at full power for three minutes duration with no 
overheating or problems. I am thrilled to say the least. I can now move 
forward with doubling my NST and getting some really good output. I'm sure 
all you expeienced coilers find this old hat but for us new guy's "God this 
is awesome". I feel like Dr. Frankenstien, I want to scream, "It's Alive, 
It's Alive".

Thanks again,
Emmett
