Greetings all, Yesterday I took my wife to the Omniplex Science Museum in Oklahoma City, OK. There was a Tesla Coil there donated by someone in OKC who I would like to ask a few questions. The coil was a 4" secondary with commercial caps and some form of NST transformer I think, possibly 12kv 120ma, but I am unsure. If anyone knows who constructed this, or any further specs on it, please let me know! Thanks again everyone! -Jeff Corr
