My first experience with high voltage, was two pins from a vertical canned multitap toroidal transformer on top of a homemade old DC power supply (attached to) an even older tubed multiband 12 volt auto AM receiver back in the early 1960's. Was reaching behind it to unscrew a pl-259 antenna connector and the ultra sensitive spot on my right wrist contacted those two pins. The resultant shock threw me back about 15 ft against the opposite wall in my bedroom (funny thing muscle contraction and adrenaline, huh?) and I sat there shaking with a gawd-awful funny taste in my mouth. It took quite a while to be able to stand, and weeks before the two burn marks on my wrist to (sort-of) go away. I'll certainly never forget that experience, that's for sure. Funny thing about electricity is when it is properly controlled, its great. BUT when its uncontrolled, quite the nightmare to many! Unforgettable, that's what it was.... (there's a song in there somewhere)...
