Last week I picked up a used but in perfect condition high voltage

Try doing that with one of your BnQ ten quid specials.

Pretty useless for measuring things like CRT HT, though. Input
impedance is too low. A similar probe on a 2 quid DVM will be fine. ;-)

Yeah, go pick on something that has like microscopic source impedance
why don'tcha? Please note: I still keep a couple of DVMs and the really
important thing is the ***PROBE*** - and having the balls to use it at
32kV (which TBH I must admit I don't have). But it is *well* out of DIY
range, let's face it.

At one time measuring CRT HT would have been DIY for those who fixed or
built tellies. I had a Heathkit valve voltmeter (with HT probe) for that
job. Still got it. But it doesn't get used these days - any more than the
AVO 8. ;-)
