Thank you very much for this Gary, I missed the part about being a SRSG! Good call!

Subject: Re: [TCML] Is this still correct, javatc
Assuming you have 60Hz power, for a 15/120 NST power source, a .031uF cap
is correct if you are using a static gap, but for a SRSG, you need a much
larger value. I think .055uF is about right. There is great danger if you
use too small a cap with a SRSG, it will charge to a voltage far in excess
of the NST rating, endangering both the NST and cap. I can't
emphasize this too strongly - having a PROPERLY SET safety gap in parallel
with the SRSG is mandatory. If your safety gap insists on firing, it may
mean that your cap isn't large enough (resonance issues aside).
