My old HV scope probe has a resistor in it that's several inches long. It's
rated something like 40kV and several rings in front of the handle to prevent
arc-over.
Which is why you use a string of them in series for this sort of thing.
With appropriate insulation, I saw glass tube used in a physics lab.

Nice to have my clock back.
Turns out the trace from blanking from pin 9 of the 74HC74 takes a very
long route around the edge of the board in reaching pin 2 of U17
(6N137). There

Note that many resistors are rated at only 150V, and aren't suitable for high
voltage service like this. There are, of course, resistors with sufficient
voltage

There was a small defect in the copper trace
