years  ago, I ran an 8" coil,  with a 25" winding length with #20 wire at approx 5Kw input.( seeTCBA News Volume 13,#4 ) Id like to stay with the lower profile (3-1 ).
 
           didnt know what problems id have using that smaller wire .....................> Date: Sat, 22 Sep 2007 17:54:14 -0600> From: tesla@xxxxxxxxxx> To: tesla@xxxxxxxxxx> Subject: RE: new secondary.......
