Need some help with my topload Answered
I have recently completed a tesla coil, but im having some trouble with the topload. I built a toriod of automotive preheat flex duct. It helped to increase the spark length from around 1-1/2 inches to 4-5 inches. The problem is, it is discharging from the secondary coil to the primary, ive tried a couple different things an it does the same thing. If anyone can help or has some useful tips or advice, they would be very much appreciated. Many thanks in advance.
