<the safety gaps. I still shunt each xfrmer lead to ground with 500pf!

Could you go into a little more detail why you no longer use safety gaps-
how do they do as much harm as good?
Is it because you use more rugged potential and pole types or do you
disregard the safeties with neons too?
I understand the use of 500pf caps to ground, do you rely on these to
shunt nasties away from the transformer?
