The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
Is TC output from toroid really AC? or HF pulsed DC?
Transformers cannot produce DC. This is because even a pulsed DC primary current induces (at the trailing edge) a reverse current in the secondary from the leading-edge current.

This reminds me, I got zapped yesterday by a new drsstc I'm building. Having coupling issues. Went from toroid to left hand then out my right hand to primary. Yes I felt that and it hurt.

How long is the arc in your setup mat?
I only know values in volts, I don't know what realistic values to put into the other fields would be, why cant battery's and stuff have current measurements on them as well as volts, would make it easer understanding such stuff.
lol, I was never talking about only HV from post 1.

Things aren't rated in amps, because there is nothing to rate. It will put out as many amps as are necessary to put out the stated voltage, up to the point where it can longer keep up with the load and the voltage starts to drop.

What setup? From that particular burn? It was a CW discharge brush about 2" long.

Yes you do, it's easy! If you've ever grasped the probes of a multimeter in each hand, it can give you a ballpark figure of the resistance you might expect between those two points. As soon as current starts to flow and burn things, or if you penetrate your bloodstream, that changes, but:
Say you measure 100kohms between your hands, and imagined touching a mains/live wire when its voltage is at the peak in the cycle (340V), you could expect a 3.4mA of current to flow.
Say you wish to calculate what resistance would be needed to allow 30mA (typical figure that might fibrillate/interfere with your heart badly) to flow, if you came into contact with a mains/live wire when its voltage is at the peak in the cycle (340V), you would calculate a resistance of 11.3kohm is needed... which is pretty easy to achieve if your hands are damp, sweaty, or you pierce the skin.
