Tesla used spark-gap driven oscillators (I believe). Normally the turns-ratio of the xformer, primary to secondary, determines the step-up (or step-down) ratio, but this is not true in circuits that are in resonance. (Or so the book on Tesla claims.) Apparently you can get "extra" step-up in a resonant xformer. Tesla's spark-gap apparatus was self-resonant and so tuning wasn't as critical as if you had an oscillator driven by a fixed reference freq. Then you would need to tune the osc or the coil to each other. -- - John Logajan @ Network Systems; 7600 Boone Ave; Brooklyn Park, MN 55428 - logajan@ns.network.com, john@logajan.mn.org, 612-424-4888, Fax 424-2853
