Default Equalizing resistors needed for HV diode string?

Well, I was hoping the answer would be something like this. I expect a good
nights sleep tonight, unless I think of something else to worry about!

No need to use the equalizing resistors. Modern diodes will "zener"
when reverse biased beyond their rated PIV. This will distribute the
inverse voltage across all the diodes. Just be sure to use enough
diodes in the string.

I agree with Ed. Older diodes would breakdown, modern diodes
will "Zener" and basically self protect in a series string.
