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.
