Hmm, if a fuse is made to be a sacrificial component, as proffered by georgehifi, then wouldn't it make sense to make one of higher quality?
It wouldn't degrade as quickly, if ever.
As for the ones that blew instantly, aren't those rather rare compared to the vast majority of fuses sold? And didn't someone, earlier on in this thread, say that not all amps turn on the same and the inrush of current is not the same from different makes? I seem to remember someone talking of a brand with different models that behaved differently. Fuses blew and fuses didn't simply dealing with different models of the same component. And didn't someone offer that going up just a bit in value seems to do the trick for the ones that easily blow without detriment?
Some tubes fail soon after insertion for no apparent reason. Some other components do as well. Crappy fuses have been made for a long time so it's rather easy to assure the most basic performance needed during manufacture due to the lower standards involved. Pound them out. Almost uniform performance after purchase is a given and nothing to really brag about.
Some failures are to be expected. So what? People have gotten their money back or the fuse replaced and viola! It works.
All the best,
