Is there a solid fuse-like item that I can use in place of a fuse, to bypass it?

@nonoise

As usual, you are missing the point....

If the corrosion is bad enough to the point where it introduces excessive resistance to the circuit, everything will be affected of course. The device may not even power up properly, let alone just the sound aspect of it.

@cakyol , 

Again, like every time this has come up (just check out the threads folks) you miss the point you make quite intentionally. The amount of corrosion you speak of would be a ridiculous amount to do what you say it will. Again, not the point I was making.

To say a fuse has no effect on the sound and if it did, it's due to a worsening of conductivity, then please explain how a fuse that works the same as a bog standard one, made of better and purer metals, couldn't conduct better.

Designers never looked past the conventional wisdom that all a fuse is good for is protection so they use the cheapest crap they can find, made of very poorly conductive properties. 

Anyone here knows that no fuse gives one the best sound possible. Amp designers (it's out there folks...you look it up) has related how an amp they designed that sounded wonderful, ending up sounding worse once they implemented the fuse for production.

I believe that Ralph, a wonderful amp designer who posts here, doesn't use fuse protection and uses circuit breakers in his designs, which is one way of getting around the "sound" of a fuse.

This discussion has been going on for decades and your side never seems to get it and gets their kicks on forums like this for questionable reasons.

All the best,

@nonoise

A bit more education for you and the fuse worshippers.

Below is a power supply designed by Nelson Pass for a few of his amplifiers. Notice the ample use of thermistors in his circuit to perform inrush current protection. In addition, look at the stability resistors in series on the secondary side of his supply.  Examine and understand that the thermistor in series in the AC circuit is almost equal to many fuses in series, as far as the resistance is concerned.

@cakyol ,

Silly boy, I don't worship anything so talk like an adult (that's a sign that you're losing the argument, which there has been many...again folks, check out the past threads).

I don't read schematics and designs. Not anywhere near versed in it. Doesn't matter a whit. I use my ears. Have you ever tried to listen to a fuse, just for sh*ts and giggles? I did, and there is a difference. Cheap and easy enough a thing to do instead of banging your head against the wall.

All the best,
Nonoise

"I use my ears...."

As I said before, a visit to an audiologist will help :-)
