FWIW, and right or wrong, I've used ordinary 1 or 2 Amp 3AG fuses 
in the HV lead to an amplifier to protect the tubes.  Of course one would
use an ordinary chassis mount fuse holder!!  I placed the fuse inside 
the "sealed" power supply interlocked cabinet near the HV output 
connector.  It worked when needed!
