Mark,
Years ago when I had my TR3, it blew that fuse. I replaced with identical
and never had another issue. That would have to be 15+ years of use. I
can not say now, as I sold it a few years back. I am guessing that the
fuse takes a good deal of abuse from turn on cold filament surge as you
say. Not sure if going to a slow blow would be needed based on my
experience.

Dear folks,
I was just aligning a TR-3, and the 8A fuse blew. This fuse had always
looked pretty bad anyway. I suppose it gets a certain amount of abuse from
the surge until the filaments get up past their cold resistance. I have
replaced it with a 8A slow blow, and the alignment now in the final steps.
Is this OK, or should I use fast-acting fuse??? I suppose there could be a
filament-to-cathode short on a tube also that would cause this ???
Thanks fellows,
Mark
