Greetings, I sent this post yesterday, but it got lost in the void somewhere. I'll try again. I have a roll of 1/4 in. solid copper wire. Is this satisfactory to use for the primary?? My secondary is 2 1/2 in. dia. with a 24 in. height of 24 ga. wire. I will be using either a 15 KV-at-30 ma. or a 15KV -at- 60 ma. NST. I have both sizes. Please bear with me till I gain a little more knowlege about TC's. Thanx George
