RE: Static Spark Gap



I have to disagree with the below suggested gap setting.  .02" is a
reasonable gap for each gap in a multiple stage series gap if the total gap
adds up to .15"-.30", but for a single gap this is way too small.  A single
.02" gap will work to an extent, but performance will be poor, as
performance directly correlates with gap width (as does the voltage and
stress to NST's and caps!).
