Hi Folks,

At the end of last summer, my first light experience came to an abrupt
end with the demise of my 12/60 NST. Having heard so many endorsements
for MOT based supplies, especially their hardiness, I decided to give
that a try. I recently completed construction of a 4-MOT supply and
fired it up for the first time this week. You can plant me right on top
of that MOT bandwagon. The results (using 81.8nF MMC, 3.875 primary
turns, trigger gap, and some ballasting---see full details at
http://home.earthlink-dot-net/~mjstrube/tesla.html) were spectacular. I
routinely run this thing for 15-20 minutes continuously (wearing a mask
to hold off the ozone) with great performance throughout. I have to keep
the input to about 90 V or so or the streamers hit the ceiling too
often. Should be fun to fire it up outside at full tilt. This thing has
far outstripped the expectations I had. My remaining NST will surely be
gathering some dust. I've taken a few pictures of the construction of
the supply as well as some pictures of the coil in action using the
supply. They appear on the website.

Cheers,

Mike
