Could you guys explain this back of hand thing - I'd be a bit reluctant to touch anything I was doubtful about? I did get pushed across a classroom once by a badly wired record player, and wouldn't want to repeat it.

My Dad got a small shock from an army lorry once as part of his training (by accident, he wasn't supposed to find out that way that the NCO had stuck a cigarette paper over some crucial connection), but that wasn't mains.
