Fuses fuses fuses


Ok, this is about fuses

1- a standard Bussman fuse is UL approved. Are any "high end" fuses UL approved?

2- do any component manufacturers supply their gear with any of the usual suspects of high end fuses as opposed to a standard Bussman?

3- let's say fuses do make a difference. Given incoming power is AC, why could fuses be directional? 

Not meaning to light any fires here- 

thanks in advance

I hope you guys are listening to music while you are debating fuse directionality. Otherwise, your just wasting precious time.........

Happy Weekend to All...........
Thanks for the concern, ruebent. As for myself, I’d be listening to fuses this weekend if I had any fuses.

>>>>>All we need? If it’s so easy to measure why don’t you or one of the other naysayers measure it? You’re just guessing. Why is it the folks that are already on board the fuse directionality AND Wire Directionality train are supposed to be the ones to measure it?
I have measured it, and often because its so easy. Takes out the guess work. Why people might want to measure it is if they want to see how this actually works with their own eyes (and ears). Its pretty powerful when you can confirm with a simple measurement why it is that reversing the fuse can have an audible impact and its something no-one (not even naysayers like yourself) can take away.
To clarify this more, it "maybe" only audible if the supply stages after the fuse/holder are NOT regulated. Most sources, s/s preamps are so it shouldn't be audible .
+1; Regulation does seem to help. We don't hear any effect in our MP-1 preamp which is very tightly regulated with plenty of headroom.
Sorry if I put words in your mouth. I appreciate that you have clarified what I thought you meant.
No worries! Happy to help out.
Totally agree. They refuse to defuse but choose to infuse an effusive obfuscation instead. Obfusely everyone knows a fuse when flipped around is an esuf which sounds different. Now you can't argue that
+1 and really gets to the heart of the debate on fuse threads.




for the directional fuse people, there are elementary electronics course on the internet for free

MIT also has a nice set of free physics course for those with a few more neurons available
