Yes they do. I used one in my Drake L4B. The stock string had an intermittently open resistor causing intermittent plate voltage reading.

Mouser carries Ohmite flatpak HV resistors; Ive been using them to replace
the old carbons in many amps.

I am installing a meter to measure plate voltage 1-5000v@ 1a dc, the meter
has a 1ma fs rating. the serial resistance I have made up in the past has
been 3 watt metal film resistors in series. since they can only rated for
200v per resistor it takes many to do the job. Can some other resistor type
with a higher rating be used in a safe manner for this purpose?...tnx,
Doug,w9iix
