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

In the event of a surge, will transistors within the amplifier not get fried anyhow? thereby acting like fuses anyway?

Do power amplifier fuses ever blow while leaving transistors unharmed?

I have an idea, replace the transistors with solid copper bars too!

In the event of a short you have spontaneously very very high currents which can explosively vaporize metals. This type of thinking is madness.

Fuses are life safety and property safety devices which should not be compromised.  Ever.

Many years ago I picked up a Dan Electro guitar amplifier, a small tweed combo. I brought it to a friend’s house along with my guitar. (Les Paul BB) He had an EB3 (no amp) I was nice to leave it with him, first mistake. Second mistake was I brought a Big Muff given to me, which I forgot. A few days later he dropped the amp of at my home (not working and without the pedal, I wasn’t home) So I phoned him, "did the fuse blow"? "Uh ... yes" "Did you replace it with aluminum foil"? "Uh ... no. Uh ... I mean the fuse didn’t blow" 🙄 End of story is I donated it to my Amp Technician. Lost a good amp and lost a bad friend. 👎👍

WARNING: there are several people here on this thread that are recommending replacing a fuse with solid material (whether they are serious or joking). This is not a good idea. The idea of a fuse is not to protect your equipment, but to protect your environment against fire. When a fuse in a preamp/amp blows, it means the device is trying to draw more current that it was designed for. For example, if an electrolytic cap burns through, it will "short to ground" and cause the device to pull as much current as possible.

So, many people are saying "your fire protection is at the main circuit breaker". This is only partially correct. For things such as a garbage disposal - this is a motor and will definitely trip the main circuit breaker because of how much current it can actually pull down the line.

Now let us look at something like a preamp. It has an internal transformer that will convert the 115 volts A/C to something like 15 Volts AC - a voltage that can be used by the DC regulators. The transformer is also not that big - usually not larger than 50 VA. This means that the transformer will only be able to pull and provide current for 50 watts. So, if something shorts inside the preamp and causes it to pull everything it can, it will still only pull a limited amount of current. The main 15 amp circuit breaker is NOT GAURANTEED TO TRIP (since 15 amps is basically 1850 watts of power). This means your little preamp can start a fire if you have a "solid block" in place of the fuse.

4 ga jumper cables Make sure that you are bonded well to ground.

Better sound if you pull the batteries out of all smoke detectors.
