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?

quench the arc very fast, but are quite expensive.)
Snip: It would seem to me that a high voltage fuse located after the filter C, and
in series with an appropriate glitch R, would provide increased protection, even more so if the filter C is large in capacity. Is this reasonable / practical?
