Dan -

Welcome to the coiling world. There is an on-line easy to use computer
program at

     www.mgte-dot-com

Click on Tesla, then JHCTES (Books)
Go to bottom of book page and click on the JHCTES Ver 3.42 program.

Enter
Primary .009 - 5.0 - 3.0
Secondary 1.5 - 1000 - 68 - 0 - 12
Click "Calculate" and you will get 319 KHz - 8.9 pri turns - etc, etc.
The wire is 28AWG and toroid 3" x 12"

If need to change any of the inputs, no problem, because after you make
changes and you click "Calculate" the computer will redo all of the
calculations automatically and give you new outputs that will always be in
tune. What could be easier? The MMC caps are the best way to go. Buy 10 CD
.15uf, 2KV caps and connect them in series with 10 meg resistors. This will
give you .015uf 20 KV, .01875 16 Kv, etc, cap values to play with. Have fun.
Let us know how you make out.

Hello, I'm part of the way done with building my first coil. I've sat here
in front of the computer for hours trying to make sure of all the right
numbers and measurements and such. I was just wondering if someone could
tell me if a .009uf 13,000v capacitor will be enough for a 9kV 30mA NST. Or
does that sound like someone who stayed up too late working on this thing?
Thanks everyone.

Oh and if that does sound about right, would anyone be so kind as to help
me out with what kinda caps I should use? I wanna be difficult and build a
MMC, I think they look cool and they seem more accurate. Thanks again.
