Re: [TCML] c/w multiplier coil

Hello Everyone,
Some time ago I built a Crockroft-Walton multiplier to quintuple the
voltage of a power supply for use with a small coil. Recently, the
multiplier was hissing and losing a lot of power to corona. So, I
decided to operate it under oil in a coffee can since it is a small
multiplier. I sunk the whole multiplier in a coffee can filled with
motor oil. The can is metal, but the components are all at least 3/4
inches from the sides. The assembly worked exceptionally the first
several times I ran it. However, when I power it up now, there are no
sparks from the coil. Directly shorting the multiplier yields only 2-3mm
long sparks which are very faint, whereas before it would produce 1.5in
sparks when shorted. Also, when powered on, the transformer makes an odd
clicking noise which I did not notice before. Does anybody know what the
problem is here?
ALmost certainly you have some sort of arcing internally. While the oil
suppresses the evil hiss of corona, that doesn't mean it's not still
arcing somewhere. You might be building up charge on some part and it
periodically arcs over.
Try it in a non-conducting can to start.
