Hi Reinhard,
We are talking about a totally different circuit. My
original point was that you cannot build a low voltage coil because the
200-300V people were disscussing as possible with a flash tube will not break
it down. You are talking about using it in a normal NST powered coil which
has enough voltage to break it down but does not need it because it already
has enough voltage to run a conventional spark gap.
