Re: 2467B focus/astigmatism anomaly...
I think it's a viable technique; although there are more things to remember not to touch. Only LOOK at the null detector, don't try to fiddle it...toggle quoted messageShow quoted text
If I tried this, you better believe I'd have one hand behind my back.

If you have another power supply that can make 15KV, you could assemble a differential voltmeter using the supply, a battery-powered voltmeter as null detector, and another voltmeter to measure the supply output once you have it nulled. The detector should have autoranging turned off, and have protection diodes across its input.
