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?

it's what frustrated lab technicians and high school teachers do because they never made it as real scientists. Big noting themselves on forums makes them feel empowered.

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

I agree in principal but disagree on the last bit. It isn't a small chance that the insurance would be invalidated it is a very real possibility.  Waste money on something else like having the electrical utility replace your house supply line back to the nearest pole with audiophile approved wire. It won't make any difference either but after spending thousands doing it I can almost guarantee that you'll think there is a big improvement.

Looks like it’s currently out of stock, but here you go. I use these in my Magnepan 1.7s. I’ve owned Maggies for 40 years and never blew a fuse, so didn’t feel that I was taking much of a chance. Bypassing them made a significant sonic difference. :)

Noice!

I would not have guessed you were a BR fan. 

I agree that bypassing a fuse takes a step towards unsafety, so i will keep the two main 7A fuses in place. But for the other seven small amperage fuses...I’ve bought a few 6mm dia. copper rods from aliexpress and aim to whip up some small copper fuse replacements.

I’ve restored my amp with all new resistors, diodes, capacitors, and all of the power supply transistors, plus i listen at a quiet volume for only short amounts of time. I don’t feel that i am putting the power amplifier (Yamaha PC2002) under any stress at all, and it always remains cool, so i feel safe bypassing the internal fuses. I planned on using the copper dummy fuses in case i want to sell the amp and easily revert back. But who knows...i kind of like the idea of removing the fuse holders and just soldering a thick gauge copper into their places.

@ an above poster, the Nelson Pass amplifier you linked is one he designed for the DIY community, so yes it does have fuses. But you’ll see that there are other of this designs that don’t have fuses, for the very same audio-degrading reasons that have been mentioned in this thread.

I don’t claim to have any revealing system. But by taking noise reduction measures, one step at a time, from different areas of your audio chain, me or anyone can systematically sensitize their system such that if a fly lands on a wire and takes a crap, while you’re listening to music, you may jump back and say "wow what the hell was that?" or "wow, i’m hearing things in the music i never heard before!"
