[AMRadio] COLLINS KWS 1 power supply questions

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!

Subject: [AMRadio] COLLINS KWS 1 power supply questions

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?
