I'm not going to waste another minute of time trying to eke some sparks out of these transfomers! I have used voltage doublers, removed all of the shunts, and added more capacitance to the filter to no avail. Next stop is a PIG! This will be the only way I can charge this brute of a tank capacitor I built efficiently. I can't wait until next month. Then I can see if it will fit under the christmas tree!
