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
NOT
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!
