I have no experience with gaps for anything larger than an NST power supply
so can't comment on the series quench configuration. But based on my
experience, I suspect the use of PVC in proximity to the gaps is a less
than ideal idea. Even using a single NST, the white PVC turns an
unsightly brown color due to the intense UV emitted by the gap. I don't
know how its insulating or mechanical strength might be affected, but
better to use G10 if available.
