The message
from tony sayer contains these words:

We used a thing called an earth stick when I worked with TV transmitters
15 off kV at serious currents. Lotsa charged capacitors that would
regain a bit of charge.

Ah yes, that's a nasty habit of capacitors, isn't it. TV tubes can do
the same. You earth the HT nipple on the side, then a few minutes later
the sodding thing's live again - you know this 'cos it's given you a
heck of a belt.
