Original poster: "Hajdrowski, Leo T." <leo.hajdrowski@xxxxxxx> Hello, I just started building a coil with my son and have looked at dozens of schematics. Half of them have the main capacitor in parallel with the primary coil while the other half have it in series! Also, half the schematics show the spark gap between the output of the NST and the capacitor, while the other half show it between the capacitor and the tesla coil primary! Does it make a difference? Which one is correct? Thanks....Leo
