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  I replaced the pre amp with a newer version of the pre amp and it has the same fuse value.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.

... here's some constructive criticism, based on the assumption that, in order to sound remotely palatable, audiophile grade amps need AC mains to supply perfect platonic ideal archetypical sine waves, like god's flatulence ...
I have no idea what you are talking about and, I suspect, neither do you. Such nonsense.

It is a mis conception that a faulty component that takes damage when its fuse does not blow, will instantly trip a 15A or 20A circuit breaker before enough damage is done to start a fire in the component. In most cases it will not. If your faulty component doesn't blow a 10A fuse (where there should have been a 3A or 5A fuse) before causing damage or fire, don't expect it to trip a 20A circuit breaker.
Agreed 100 percent. A circuit breaker's job is to protect the wire in the wall. Nothing else.
