We Need A Separate Forum for Fuses

The AC signal continually reverses direction, at the rate of 60 cycles per second or whatever. That’s why it’s called alternating current. It the signal first travels one direction then the other. It is therefore bi-directional. It’s not non-directional or indirectional. It’s not continuous as I’ve seen you say somewhere.

But when we talk about fuse directionality we’re referring to the idea that the fuse sounds better when the fuse is inserted in one direction rather than the other. A fuse in an AC circuit is directional because what you hear in terms of sound depends only on the signal during the alternating cycle when it is traveling toward the speakers from the amp or to the amp from the wall, whatever. You don’t care what the signal sounds like when it’s traveling back toward the wall outlet. That’s why fuses in AC circuits are directional.

You guys were paying attention.
I became overly excited when I thought we were making progress.
I still find,

"so small as to be insignificant"

to be the salient point of the entire statement

...when taken out of context. It's just like removing the fuse from the equation to make a point have more significance than it does. 

Again, some amps designers say that using no fuse sounds the best but it has to be used, for safety purposes. I find that to be quite a salient point. 👍

All the best,

Isn’t the type of coal used to heat the water to make the steam that drives the electric turbines at the power station more significant than a fuse.
