These are great. http://www.dedicatedaudio.com/inc/sdetail/154

Problem solved if you are able to DIY.

A power cord tuner?

That's better, that's actually something useful.

Haha square peg, round hole?

Solution, BIGGER HAMMER.

Easy - unsolder the clips, solder in pure silver sheathed wire from the board to the fuse....would I do it - NO WAY!

Perhaps you could send the part to Bryston with your amp and ask them to do it for a nominal fee...perhaps they could test your amp before and after to see if there were any measureable improvements with the new fuse holder and new fuse. Questions, questions, questions....

why not yust roll your own?

according to this chart:
(http://en.wikipedia.org/wiki/Fuse_%28electrical%29)
Fuse wire rating (A)    Cu Wire diameter (mm)
3      0.15
5      0.20

get copper (cu) magnet wire, and attach to the fuse points. if you have smaller than 3a fuses, get thinner wire - magnet wire is awailable as small as 50awg...

I bet in a double blind test between "audiophile" fuses and "normal" fuses no one could hear a difference of any statistical significance.

Pez · « **Reply #51 on:** 26 Jan 2012, 11:46 pm »

I bet the same is true for your audiophile grade amp vs a crappy pioneer receiver.

Does being a volunteer give you a license to be a complete snot? Perhaps your immature nature just always shines thru.

For me, inserting an isoclean or hifi tuning fuse elicited fundamental improvements in every instance. Its easy say the same about the Longhorn mod on any cartridge i've owned.

Controlling resonances is important all throughout our systems. Why support it on one end of the chain & not the other? The idea is to strengthen the entire chain, right?

With both tweaks voices get clearer, the recording snaps into focus that much more in a rich, harmonic way.

the AMR fuses are filled with nano fluid. neat.

Wut, is it not true? I mean if you're going to say you want proof that high end fuses make a difference, why can't I ask for proof that amps sound different? The comment I made was not in jest. There have been many ABX tests which 'prove' no significant difference in amplifiers.

Sorry that makes you so upset.

The only problem I can see with trying to roll your own fuses is duplicating the alloy used in the fuse
element. An internet search reveals that most fuse elements are designed to have a low melting point and in some instances are the same alloy used for soldering, a 63% tin and 37% lead alloy. Unfortunately I could not find a single instance where a pure copper wire was used as a fuse element. The other problem that would rear its head would be soldering that tiny piece of solder to something in the fuse holder.
I have heard an improvement in the sound of a fuse when I stripped off the nickel plating exposing the brass body and treated the fuse with Caig ProGold. The best sounding conventional fast blow fuse I found had a lightning bolt shaped element. Of course Bussman stopped making this shape of fuse element a few years ago.

the biggest beef I have with the Acme fuses is that they actually blew for no reason sometimes when I'd turn on my amps. I can understand if I had te wrong value or if it blew for legitimate reasons, but these suckers blew for no apparent reason.

That story makes me wonder if any of the audiophile fuses would actually blow when they are supposed to blow. I don't doubt that they are a sonic improvement, but I would always wonder if my gear was properly protected.

"an internet search..."

of course, that's where i got my info, as well. who knows?

all i know is that wire fuses are relatively old technology, replaced by what we see now. but, regarding the need to duplicate the alloy of the new style fuses, the info i got regarding size to use was strictly referencing copper. not sure how one could test it, other than to experiment w/something of a known load, and use smaller wire, and see if it blows or not. or maybe contacting a mfr directly, and ask their tech engineers. regarding soldering, it seems it would be easy enough to solder directly to the board where the fuse holder is soldered, or simply use a non-metallic dowel of wood or plastic, w/the wire forced to the fuse connector, yust like a regular fuse. i actually did this once as a temporary fix, w/a fine strand of copper, when a fuse blew in one of my step-up transformers, and i didn't have a spare fuse handy...

ymmv,

The copper fuses I could find were rated for 600v and 225 to 450 amps. See link below

I don't think this is what you had in mind.
