run into this! Except one doesn't need a high-impedance
meter for it...I've seen them somehow recover enough charge to
produce a spark when re-shorted. It's very odd.
Anyone who has done a lot of work on CRTs has experienced this.
Disconnect the anode lead, short the anode cap, come back in a few
minutes only to get another spark.
Yes. I used to work on TVs a lot when I was a kid; I'd dig dead
ones out of dumpsters and (sometimes) fix and sell them. I got two
or three good jolts from CRTs before I figured out what was going
on. I never did quite understand how it happened, though...do you
know the physics behind it?
