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


Hi All,

instead of using a "gourmet" fuse in certain situations, I want to bypass the fuse entirely with a solid piece of metal. I also want to avoid soldering-in a piece of wire in the fuse’s place.

Are there solid pieces of silver or copper, the same size as a fuse, that i can swap into a fuse holder?

Why do you want to do that ?

Do you want to give your insurance company an excuse not to pay you if your equipment starts a fire, albeit a small chance ?

Besides, contrary to almost everyone who think they can hear better than a dog and believe that a fuse changes the sound, the claim is snake oil, it has absolutely no effect on the sound. So, by bypassing it, you will not actually improve anything.

The only reason fuse manufacturers fill their fuses with sand is for safety so that the glass does not shatter with a sudden temperature rise. It has nothing to do with their worry about reducing resonance or improving audio quality.

@theaudiotweak, @auxinput 

Fuses do not affect the sound.  If they did, do you think manufacturers of thousands of dollars' worth of equipment would not already put some 'audiophile' fuses in them to make their equipment sound better ?

They do not because fuses are there for protection.  Unless they are corroded, they do not under any circumstances affect the sound.

@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.

@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.

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

That is actually a great idea.  As long as the amp is not a class A amp, it can be permanently left on as well, which will avoid inrush current damage, in case the amp is not protected against it.
