Hate it when the dam fuses blow when they are supposed to be sounding good. It’s almost like they are designed to to that! Oh well break out the credit card.
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 I replaced the pre amp with a newer version of the pre amp and it has the same fuse value.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.
