These are the 3 capacitors I rebuilt last 1998 spring and they are the only ones that survived the test. Each 15 gallon drum contains 100 folded pieces of aluminum foil, 200 pieces of plexiglas and 7 gallons of transformer oil. Each capacitor has .023 mf. of capacitance. Each drum was put into an old transformer case and all the air was vacuumed out. Transformer oil was then heated to 150 degrees Fahrenheit and allowed to be sucked into the drum under a vacuum to eliminate any chance of there being air trapped between plates. The tall pipes on top of the drums are for the expansion and contraction of the oil during hot and cold days, They have a sandwich bag on top that is twist tied on to keep out moister and dirt, but in case of capacitor failure they blow up like a balloon, pop and let out the expanding gasses. The long white PVC pipe with copper ends is my link from the capacitors to the rotary spark gap. It is built like a capacitor to eliminate loss of power from the capacitors to the Tesla Coil. I used to run cables from the capacitor to the coil but it always seemed like I had to push more and more power to get any results. I noticed that after cables were more than 4 foot power dropped off dramatically and the high frequency dampened out and at 10 foot you had no power left, but with the capacitor type connection 20 foot connections were no problem. This is the 2nd best improvement to the Tesla Coil performance that I have come across.
