Not meaning to add confusion to the issue but the current is alternating in most circuits where fuses are used (i.e., AC circuits), thus the net velocity of current is actually zero for almost any delta time.

Geoff, No documentation like this for an example http://www.littelfuse.com/~/media/electronics/datasheets/fuses/littelfuse_fuse_325_326_datasheet.pdf... I purposefully picked the ceramic body ones - this way - should you decide to buy some, you can color them with your Crayons to any color you'd like Good listening Peter |
Stubborn cuss, ain’t he? God gave you two ears and one mouth for a reason. I don’t subscribe to any fuse or cable manufacturer that doesn’t control directionality. I don’t even care if they’re UL listed or not. Whaddya think about them apples? 🍎 You are free to do whatever you want. Live and let die, I always say. |
@falconquest - in response to bumped up fuses. I did say "generally speaking" and also said "there is a point where it doesn't make much difference". I have heard definitely improvements on bumping up a 1A fuse to a 2A fuse in a preamp. Heck, I have even heard improvements in going from 1A to 1.6A. The sound with the larger 2A just hits with more authority, more power and better resolution. However, that's the most I will go. I have seen some preamps that use a higher amp fuse (such as a 2.5A in a Krell Phantom), so a 2A is not out of the ordinary. Usually, these larger amp fuses make more of a difference in preamps that use Class A circuits because they are such current hogs. Things that use normal op amps or a small amount of op amps may not benefit as much with the larger fuses. The difference between 6.3A and 8A is going to be a lot less - probably too small to actually hear a difference. But there could be a -very- minor improvement. As far as these NASA comments, either they are a troll or coming from an inexperienced point of view. NASA will have completely different requirements for their fuses - such as extreme reliability, exact breaking/melting point, ability to support high speed digital circuits, etc. They will not have the same requirements as far as allowing the voltage into an analog equipment to sound pleasant or with a specific character. |
