100:1 scope probes

[pamphonica]

I most definitely would not try these at 2kV! My recommendation for reliable probes for use on vave gear is an old-fashioned Tektronix probe, like the model 6006.
Often to be found in junk boxes at electronics table sales.
They are the big chunky ones in the middle of the photo here:

They have a rating of 600V and I think I believe them!
