[TCML] how much does secondary diameter affect efficiency?



James, I just build a SGTC at 12KV and 120mA and I lknow its not quite
there, but I would jsut plug both the 4.5 inch od into JAVAtc and also your
6.5 od and see what you come up with.  I used a 4" pvc 22" wound with 26awg
1240 turns.  Had great results, pushing 43" with a really icky looking
topload.   http://www.youtube.com/user/hatto018?feature=mhee  you can check
it out.   Thanks!
