So done with audiophile fuses

The journey started with a medium priced ($50) fuse in my power supply.  A failed rectifier tube blew that one out.  Not a fuse problem.  Next up was a blue fuse in my pre amp.  It blew and was not caused by a pre amp problem.  Apparently they sometimes are more sensitive and it was replaced by an orange fuse two values higher.  Things were going along fine.  I replaced the pre amp with a newer version of the pre amp and it has the same fuse value.  Five months latter (today) I turn on the pre amp and nothing.  it's a five month old pre amp so I suspected that it was the fuse.  Sure enough, I replaced it with a ceramic Littelfuse of the lower correct value it works fine.  No more wasting my money on unstable fuses for me.

A fuse, according to the manual, is just there as a safety device and shouldn't have any effect on the sound. And yet it did.
That, of course, is the perplexing part.  While I don't Know and won’t say that fuses have no effect whatsoever on the sound of a system, I still can’t buy that the magnitude of the effect (or improvement, or whatever) would be great enough to make me want to spend big money on a fuse.

The great part of it is that you needn't spend anywhere near the cost of a SR fuse or something even more dear in price. There are still some HiFi Tuning Silver Star fuses to be had (in dwindling numbers) for a fraction of what they initially went for. Maybe one of a value you need is still available.

I've personally tried about 4 different brands and they all had a distinct sound characteristic and didn't cost that much to experiment with. I'm of the opinion that a fuse made up of metals that are on par with what you'd use in a cable are the way to go and to stop using the cheap, low cost fuses made out of a witches brew of poorly conductive metals.

All the best,

This is just something someone would say that has absolutely no idea.

You need to be schooled in Ohm’s law/s, Kirchoff’s laws etc etc
They have to have a certain level of resistance, (as you say "poor conductively"), to blow at a certain amperage drawn through them. If they didn’t they would never blow!!!

🤦‍♂️🤦‍♂️🤦‍♂️ OMG!! fuse has to have resistance to blow.

Just more fuser snake oil voodoo talk from someone who’s out there in fairy land.
