... and *I* would be interested in reports
on any and all circuits and their longevity
in light of real-world experience and all
that mother nature (in the way of secondary
induced secondary lightning transients as
well as man-made transients in industrial
and office environments) literally THROWS
at them ...

Doesn't anybody think safety and or "isolatin
of the line" from possible human contact anymore?
That used to be a consideration (BUT with the
declining cost of technology I fear safety has
taken a back seat to features and bottom-line
cost).
