Hey Gareth..having the cap in paralell with the power supply allows the cap to discharge thru the secondary windings after the power is turned off even if the primary lead tap is disconnected for some reason. But if for some reason the primary lead tap is not connected and power is applied, an over voltage can occur if the sparkgap isnt functioning properly. When the cap is in series with the primary and the spark gap is off or not functioning well, the chance of over volting the cap is not quite so prominent due to the primaries inductance and resistance which adds "some" protection. Also, if the primary lead tap is diconnected while the power was applied in this set up, the cap can hold a charge long enuf to bite you!
Where are you considering on purchasing your NST from??? 400$ is way too much money for a 12KV unit, more like 100-150$ for a new one.

I see on they internet some people put the tank cap in parallel and the spark gap in series instead of the tank cap in series and spark gap in parallel.Whats the differince?Is there any major advantage to using a tank cap in parallel?I would like to have another go.Two of my MOTs dont work so I scrapped that for now and trying to organise another 12000v Nst for 400 bucks.IS There any reason for tank cap in parallel?
