One of the things about bipolar systems that seems to be neglected is what would or could occur if the top load polar capacity of each TC side were replaced with endings of a conventional dual plated flat capacity; essentially establishing a much tighter capacitive coupling between the systems themselves. For example if we replaced the surface area of each top load with an equivalent flat surface area and then brought these plates in closer proximity in space the conventional two plated capacity would begin to outweigh the effects of just each polar capacity alone. Indeed we should be able to move these plates so close together that the combined circuits would have too much capacity for the designed high frequency resonance dictated by L(p)C(p) and the systems would go out of resonance. There appears to be a wide margin between what is obtainable with just polar capacities alone and that of introducing a dual plated capacitive coupling between the systems. Supposedly we have equations to deal with conversions such as this but it seems very incongruous, somewhat like mixing apples and oranges, both are fruits but they don't seem comparable in actions. For instance would it even be possible to eliminate half of the polar capacity and replace the missing half with a conventional dual plated capacity? Would the secondary arcing activity be diminished? (it would seem to be so). One might instead use noble gas bulbs along the secondary circuit path to indicate the intensity of that secondary activity as was done here. https://www.flickr.com/photos/harvich/10429887684/in/dateposted-public/ Should prove for some interesting signal generator experiments.Sincerely Harvey D Norris

Hello all, I have spent the last few months tinkering with design parameters for Bipolar coils and thought I would pass along 3 that work well.
1. 5kv 10ma NST
secondary coil form = 2.5” Dia. 9 inches ot AWG28
MMC = 3.45nf X 30KV
Primary = 1/4” copper 6 inch dia. helical w/ 4 turns
Top loads = 2- 1.875 inch Dia. brass doorknobs
2. 6kv 30ma NST
secondary coil form = 2.425 Dia. 15 inches AWG 26
MMC + 15nf 20kv
Primary = 1/4” copper 6” Dia helical 6 turns
Top loads = 2 sets of 8 large canning lid toroid's topped with the 1.875” brass doorknobs
3. 12kv 30ma NST
secondary coil form 3.250 inches 12 inches AWG 24
MMC = 15nf X 30kv
primary = 1/4” copper 8.5 inch helical w/ 10 turns
top loads = 2 – 2.5” X 9” toroid’s
