Hi Chris,

I use a 5-gallon paint container for my 4-MOT supply, immersed in
transformer oil. The design can be seen here:
http://home.earthlink-dot-net/~mjstrube/Tesla/psu.html. Scroll all the way
to the bottom of the page, past the blown NST supply that motivated me
to go with MOTs.

Best,

Mike

Hi Chris
I use 4 MOT's under transformer oil in a rectangular storage container
with a lip on the inside on which the cover rests so splashes go back
into the container. Mineral oil is apparently OK but don't use motor
oil. I ruined a capacitor using this. Transformer oil is best but costs
more. see http://members.iinet-dot-net.au/~pterren/tesla_coil_latest.htm for
details. Cheers Peter (Tesla Downunder)
