[ARC5] HV Fuses: You Were Right, I Was Wrong

As you all probably remember, I did some testing using
Picofuses (tm)  to rebuild the BC-375 high-voltage
fuse links.   I "destruction tested" six or eight of them.
Each opened without problems. 

Wellll......

One opened during my 211 tests due to a gassy tube.
No problem.
I replaced it with another rebuilt fuse.
Another gassy tube, but this time....
"ZZZZZZZZZZZZZZ!!..........." from inside the
dynamotor.  The Picofuse had opened, but fully carbonized
and was transformed into a nice spark gap.  I'm lucky 
the inductive kick didn't take out any of the inductors.

So.... You were Right.  I was Wrong.  
Back to the drawing board.  
Probably try 3AG pigtails mounted externally.
