They might be OK capacity and voltage wise ,but are possibly not suitable
to handle RF current ,so when using them in HV RF circuits it might be
better to use a few in parallel.

That may well be true but thats also why I stated a case of a 200-watt
output rig where they DID work.

A year or so ago I toasted a cap in my SDG tuner. I don't recall the value
but it was one of a few in that tuner with ratings between 7.5 and 15 kV.
They looked just like you described. I order a replacement, plus
replacements for all the other HV caps in that tuner just in case. The
parts from Digikey looked just like the parts in the tuner, blue, shaped
kind of like an overweight disc ceramic.

Only a 100 watt rig, but if you hit the feedline with enough SWR you sure
can get the volts right up there.
