Re: [TCML] New Builder



Another option is the CD 942c16p15 capacitors. It is the 1600 volt version of the 942c20p15 caps. The advantage is space. You can fit a capacitor arrangement of 6 rows by 3 columns on a radio shack perf board. The 1600 volt cap will save a few bucks as well. With this arrangement, you can place a few additional connection points making the bank readily usable with different transformers, such as a 10/23, 9/30, 7.5/60 and more. If you want a visual, go here....

Very versatile!!

Hi Rick
When I built my first 15/30 coil I used a static gap an MMC with the value of 0.0083uF, and increased by 0.0083uF subsequent 30ma as I started paralleling more NSTs.  You can probably build an MMC for less than 1/2 that.    I used the 942P20C15K-F caps from CDE and they were around $3 each.  I used a series string of 18 which also gave me a safe voltage rating of 36kV.
Cheers,
Joe

Hello,
I have recently become interested in building a small Tesla coil. The only part that I have purchased to date has been a used 15kV, 30ma NST. For the capacitor, I am considering the purchase of a used oil filled GE Pulse Discharge Capacitor, Model 17L9PH, rated at 50kVDC, .043uF. Can someone tell if this is the right cap, or is there more suitable cap either homemade or purchased to match my power supply? The GE cap is a bit expensive at $125 plus shipping, but I wonder if it offers better performance than a homemade version. Thanks for any help that you can provide.
Rick
