Original poster: "D.C. Cox" <resonance@xxxxxxxxxx>The magnetic field from a primary coil is symmetrical sweeping both upwards and downwards. It is best to keep the pwr xmfr and protection circuit 5-6 feet away in a separate box. This prevents these metal components from "stealing" power from your primary circuit. Stolen power is something you won't notice and is one reason why experimenters can't get peak performance out of their systems.

Does it hurt to put your main power transformer and protection filter under the teslacoil? Some people have said not to put metal or protection filters under it and they should be put aside somewhere. This makes sense but I have seen many coils that have everything but the variac under one. In practice has anyone found out if it really makes much of a difference? It sure would make for a neat package to have everything except the variac under the coil. Kevin
