Re: MOT, and doubler

Unfortunately, there are many, many different MOTs out
there. I assume you want a matched pair. If you
e-mail me a JPG of it, perhaps I can match one up from
The diode is usually made of black plastic. It might
be a small cylinder about the size of a cigarette
filter, with axial leads of stiff wire. It might be a
rectangular plastic brick an inch or two long. Some
of them have spade terminals instead of wire leads.
Rarely I have found diodes with a hole at each end for
screw mounting, with spade terminals. It should have
been attached to the capacitor somehow.
I once built a very potent 12kvdc Tesla coil power
supply based on two MOTs with voltage doublers. The
thing sucked 20 Amps from a 240V welder outlet and
eventually destroyed my expensive MMC, but what a
performer! I still have all the pieces of it in my
garage, although the MOTs now serve as my pig ballast.
You can see it on my web site.
