I agree - the usual service engineers stance of working with one hand in
pocket to prevent a circuit across the body just doesn't work very well
with EHT voltages.

I got hit by a faulty switch mode supply (one of the first circa 1970)
which caused the supply to output 36kV rather than 25kV. I'm told that the
arc from the static voltmeter that hit me could be heard across the
service bay and when I was picked up from 8 feet away, nobody was
surprised when I announced I only wanted to work on stereos thereafter and
not TV sets! I now know what a clap of thunder inside your head sounds
like (thats all I remember!)

Thats true to this day - never been inside a TV set or CRT monitor since...
