As bad luck would have it, it landed RIGHT ACROSS the terminals of a big filter (maybe 20uF @ 15kV). The big cap blew the wrench out like it was shot from a gun...hit him in the face, breaking his jaw & taking out 8-9 teeth. It was a Collins like I'm familiar with, so prolly ran about 8,200V @ 3A or so. Owie.

Myself? Only been zapped once...an old Gates 1kW AM got me w/about 3500V @ 500mils. Knocked me right into the wall 3' behind the transmitter. I quit bypassing interlocks that day. Oh...when I was a kid I let a color TV snap an arc right thru my fingernail. Left a cute little hole. Owie.

ouch. Sorry I couldn't help but to laugh while reading that as I can picture that happening.
I've made some bad moves too and sometimes, Im amazed that I didn't get zapped when soldering/servicing under a chassis not realizing that the set was still plugged in, especially if I was working in the power supply!!!!
