Re: capacitor noob question

We carry the C-D brand 0.15 uF 2 kV caps in stock. Call tel 608-522-4378 to order.

Using a 30 mA  NST then use C = 1.57 x Cres which works out to .01 uFD.  Use
6 series spark gaps with a total spacing of .220 (total for all 6 gaps).

Blow a 150 CFM surplus fan through the sparkgaps.  We use 3 in a row and
then 3 in a second parallel row approx 1/2 apart so the fan blows evenly
through all 6 spark gaps.

Using 0.15 uF value / 15 caps in series = .01 uF at 30 kV which is perfect
for an NST rated 30 mA.

Using a 3.5 or 4 inch OD coil with an 18 inch winding length expect 24-26
inch long sparks.  Green SDR (sewer & drain) pipe from a local plumbing
supply shop.

Pri is 30 degrees.  Tune with 30 turns of scrap #12 AWG.  Final tuning
should come in around 15-18 turns.
