Got my finger and a plug into a socket when I was a kid in the fifties. My right arm stiffened and my teeth started grinding. The old man knocked me out of the socket with a wicker basket. Funny thing was I watched my father get thrown against the wall when he put his hand in an old Fada TV. Must have contacted a capacitor.
The back end of the picture tube had 15kV on it if it was a black-and-white set, 25kV if it was color.
My dad invited an engineer friend from work to our house when I was seven or so. I told the guy I wanted an oscilloscope, and he proceeded to talk my dad into letting him make one out of our Philco television.
He made a big deal out of telling me I had had had to make sure the HV power supply was discharged before I touched anything. His stern warnings made a lasting impression.
My dad convinced him to give up the project before he actually got the oscilloscope working.
I was a little bit disappointed, but he also had made me queasy... I was afraid he might break my beloved TV set! No more after-school science fiction movies! No more Jetsons!
I wanted an oscilloscope, yes, but not that much.
