Hi Mike,
If you click on the link at the top of this page, you'll see Eimac's numbers
up to 5 KV on the plate.

Above that point, rather than inserting a zener in the cathode line, I'd
suggest biasing the control grid (suitably bypassed naturally) a bit negative
to control the ZSAC and keep the resting plate dissipation within reason. The
screen may remain at ground.
73 & Good afternoon,
Marv WC6W
