[Amps] L-7 Failure, HV fuses

["Pat Barthelow" <aa6eg@hotmail.com>]

Re HV fuses:

I have seen in the literature descriptions of a HV fuse made by inserting 
into the B+ line,   a 30 guage Cu wire approx 2" long.  suspended between 
two ceramic standoffs in the amp.  Would that function as a near 
instantaneous HV fuse. protecting the tube in the event of a heavy current 
HV fault?

Snip:
It would seem to me that a high voltage fuse located after the filter C, and
