Years ago, when I did my first scope repair. I made a HV probe from big resistors from the tube area. I made it with silicon wire and the meter was connected over a trimpot at the ground site. It had crocs so I could mount them, put on the power and there was no need to touch it.
To bad it did not work as I hoped. I then learned that the HV test point can be rather high impedance so the HV probe loaded it to much and voltage dropped because the probe was parallel with the testpoint impedance. Total probe R was 100 MOhm.
A very good friend came by (he is learned me most of the things about instrument repair) and had a HV testprobe from Voltcraft as a gift to me. It is 40KV and I use it still. I also have an antique Philips HV probe. It has a metal grip. I use it now and then if there is not enough space but it was made for a philips meter that was no 10M.
By the way, not every, or better, almost no, HV probe is usable for AC ( other then very low frequency) There are HV scope probes and even those have bandwidth restrictions. I have two Tek HV probes, they are very big.
