RE: newbe needs MMC plan

Now that you know what value your tank cap should be, go to:
http://tesla.better-dot-org/mmc_form.cfm
and use the chart that is produced when you fill in the values. Select a
combo of caps and strings of caps to give you that value (resonant) or 2X
value (LTR) depending upon your spark gap. For example, I used a 15/60 NST
which requires a .0106 mFD value (resonant). But I went for a .0117 which is
probably a little less than I should have.
Make sure the voltage is at least twice the total voltage of your coil. My
tank cap voltage.
is 32KV. Photo of my MMC is at http://www.flash-dot-net/~ford29/tesla/mmc01.jpg
In mine, each board has 20 .047/1600V caps in series. There are 5 boards in
parallel.
Hope this helps.

Im trying to build my first MMC, but Im a little lost on the details (type,
number and configuration of caps). I searched through the archives and found
lots of big equations with strange variables. Im using a 15kV, 30mA NST so
Im pretty sure I need 0.005uF, and Im using a static spark gap (if that
matters). If someone is using a 0.005uF MMC that seems to work pretty well,
please send me all the good stuff (designs, cap type, cost, source) I would
really appreciate it. Im a full time college student so I need to be as
economical (really cheap) as possible. I found some good information on MMCs
at

Thanks!
