Today I touched the outside of the lampshade and got a sort of
vey
mild tingle feeling which felt "odd". When I used a mains
tester
screwdriver on the exposed metal (at the joint of the lampshade
and support arm) then it glowed as if the metal of the
Anglepoise
lamp was live.

Once had lots of problems like this, and when i got a shock off the
earth I did something about it. It turned out lots of the various earth
connections around the house were just copper cable twisted together,
so of course the joints had gone high R over time. Also the earth rod
was disconnected, so there was no E anywhere anyway. Just glad there
was no shower.
