I understand that, and I agree with the point WRT "Case 2" being better than "Case 1". But why does "Case 3" behave any differently from "Case 2"? FWIW, Richard Hulls notes indicate that "Case 3", the "Equi-Drive", is definitely preferable. This was a setup that Tesla advocated. However, Hull wrote that the "Equi-Drive" system was more prone to leave a charge on the primary cap without bleed down. Again, I don't see why. -Phil LaBudde
Phil, I did various comparisons of case 2 and case 3. There was no measureable difference in performance. I also don't see why there should be any difference. Case 3 definitely tended to leave dangerous charges on the primary caps. I think it's because of the inductive primary being situated (floating) between the two caps.
