Original poster: "Jason by way of Terry Fritz <twftesla-at-qwest-dot-net>" <jasonp-at-btinternet-dot-com> Hi all, I just built a MOT coil - 4", 2KVA, 4KV, the usual setup. I was wondering how beneficial a 400 or 800 BPS SRSG would be compared to my normal 200BPS one... Has anyone experimented? (At the moment I run a TSG) Thanks, Jason
