A CRT enters the room...
Seriously thought electrolytic capacitors need to be respected but not feared.
- agumonkey 5y agoI opened quite a few, and I wonder if they have bleeder resistors around the tube.. it's also interesting to witness a bit glass thing acting like a capacitor ps: for long I wanted to make a discharge rod but never finished it

- gugagore 5y agoHow about the electrolytic capacitor of a camera flash circuit? Knowing that they could deliver a nasty shock, I discharged one once by shorting the terminals with a screw driver. The sound of the spark, and the scorch mark left on the PCB and screw driver left me fearful of them. Or was that caused by the knowledge that I had a friend who said he put one of those capacitors in a highlighter, thereby making a makeshift, single-use, "shelf-unstable" taser?
- rytis 5y agoMany moons ago I worked at a computer service shop that also repaired CRTs. Once, as a practical joke, someone asked me to hold a lead... Which was live with around 4kV. Wasn't pleasant experience.
- dghughes 5y agoYou probably saw the tool used. A long flat blade screwdriver with a wire wrapped around it and on the other end an alligator clip chassis ground wire. It's used to pry up and remove the high voltage lead and when doing so you'd hear a loud snap!
