Re: Safety Gap =

I built my caps almost bullet proof.  They are all rated 40,000. volts each.
I want my coil to be maintenance free.  I think overkill is better than a
DEAD cap that has to be replaced.  I have not used safety gaps in so long I
have forgotten that people use them.  I assume it would be wise to use a
safety gap on caps that need the protection.  Richard Hall once said if you
build your caps with a voltage rating of 2.5 times the transformer voltage
safety gaps are not necessary.  After loosing a few caps I took his advise
and built all my caps 40KV rating and I have not lost a cap sence.
