Greg, the fuse is still in production.  Go to your local electrical supply
store and if they do not have it they can order it for you. It is called a
HVB-1.  Be aware it is not a cheap fuse so buy an extra and hope you never
use it.
Good luck!

Hi:
I finished rebuilding the power supply on my new KWS 1.  I have a couple of
questions for the group:
 
Is there a substitute for the HV fuse in the 2 kvdc line? Is the original
still being manufactured?
 
I'm going to use solid state plug in diodes instead of the 866A's.  Do I
need to disconnect the filament supply to the 866A sockets?
 
Thanks
Greg
