Hi Uwe,

If you buy the FLPS-boards, you have rewinde the core......you can't use the core like he is.
If you can buy a HF-E-core it will work too.
Our HV-coil makes about 400 till 600 Volt, depent how the coil is wind and how the ocsilator is working.
Raisetime untill 150 Volt less than 3ms, 400 till 600 Volt within 3ms
