Original poster: Skip Greiner <skipg@xxxxxxxxxxxxxxx> Hi, againYes, the correct value is 35nf. I will be using an 1,800 rpm, 4 pole, SRSG. I made a serious mistake in my first post. My frequency to wavelength conversion was faulty and therefore the secondary calculations were wrong. I have made the necessary new calculations and will probably throw the unit together over the weekend. The primary (with capacitor) and secondary (without a topload) will both be resonant at about 210khz and the wire length of the secondary will be 1/4 wave at 210khz. Will post results, hopefully next week.

Original poster: "Gerry Reynolds" <gerryreynolds@xxxxxxxxxxxxx> Hi Bart, Did you calculate the resonant C for his NST. 9000V@120ma ??Unless I made a mistake, I believe it is 35 nf. He is planning on a 35 nf cap using a SRSG (he said 4 pole rotor but didn't say whether he is running at 1800 or 3600 rpm.Gerry R. Original poster: "Barton B. Anderson" <bartb@xxxxxxxxxxxxxxxx> The NST will be fine charging the cap. You could do 120 bps efficiently and even 240 bps well.
