Don't Worry, It's Just ESD (Electrostatic Discharge)

The last part with the discharge of the caps was something we used to do all the time. We would charge up a power supply board and then set it in the scrap bin and wait for the first person to come digging for gold. --

My Dad and I used to do repair on vacuum tube equipment and I still remember the story told by one of our customers how he reached into some de-energized equipment and got across a still charged capacitor. Knocked him right on his butt!
I used to repair video arcade games. As routine practice, we would replace all the caps on the monitor chassis when we would bring one in for a rebuild. There was one style chassis in particular that had a cap that would stay charged for a long period of time and that needed shorted before handling. When I first started the job, I grabbed one of these after removing the board from the cabinet, got a hell of a shock, dropped the board and then instinctively grabbed it again to keep it from hitting the floor and got shocked again. I had a headache the rest of day! LOL.
Caps are easy to deal with. However, I've learned the hard way that one can't just quickly discharge CRTs, they actually need to be kept shorted for some time. I shorted one with a screwdriver for probably about half a second, then continued with the removal. About 5 minutes later: !f@#$u%^&(c*~!+k!
From that point, I always hooked up a jumper wire that kept it continuously shorted for at least a couple of minutes before getting close to it.--

A fully charged decent sized cap can make a MacGyver taser/stun gun. If it don't put 'em on their butt, it'll give ya enough time to get the upper hand.

Yeah, I had that happen to me a few times too. Worked like a charm, I would remain alert for the rest of the day!
