There was a jest, cleaerly recognised as such, in at
least one
service manual years ago. When it came to fitting the yoke to the
CRT, the instructions were soemthing like 'Tighten the clamp until
the CRT implodes, then back of 1/4 of a turn' :-).
Heh. I suppose you could take it as a filter: if you take that
instruction seriously, you have no business even taking the cover off
the unit. (Unfortunately there's no way to make it actually prevent
you from....)
This is very much something you should only attmept if
you know what
you are doing.
My father used to test lightbulb sockets for liveness by sticking his
finger in them to see if he got a tingle between base and side.
It is possible to do this safely. It is also possible to kill yourself
attempting it. So I would never recommend it; anyone who understands
electricity enough to do it safely doesn't need the recommendation, and
anyone who doesn't is better off without it.
