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  I replaced the pre amp with a newer version of the pre amp and it has the same fuse value.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

I just replaced all the breakers in my AC panel with solid 2 AWG copper - so far so good 🤷‍♀️

The only time I've blown fuses is overdriving my Heils....once.

My amps and receivers have thermal overload protection circuits or are fused.  The latter have Never Blown.

I would think the mfr. would know what should protect what.

So anytime y'all start farting around swapping fuses, the warranty goes 'bye bye'....if it hasn't expired.

If that is the case....you are on your own.

If you haven't dealt with the AC supply prior to it's arrival at your device, no major $ fuse is necessarily going to cover your tush....regardless of what you hear.

Unless, of course, you have a degree and experience in these affairs; then you're free to roll the dice with knowledge in hand.

Just another sad lament on another day....

I never got suckered into that fuse crap.

I don’t have problems blowing any fuses, much less $50+ boutique fuses.

Only fuse to go to heaven was a HiFi Tuning silver, after pulling it out to clean the contacts, most likely my fault as the fit was rather tight, twisting does not work. Replaced it with a Furutech one, all fine and better.
