Original poster: ben eells <squeels2171@xxxxxxxxx> I found this website that tells how to modify a NST to increase the voltage. http://www.rtftechnologies.org/emtech/nst.htmIf I were to do this with my NST's would it give me better performance? I plan on using 2 15Kv 30ma NST's in parallel for my coil, could I use this modification on both transformers? All input is appreciated.
