How it works! From a common man.

     I decided to skip the whole fuse experimentation process and dove into, with the help of a carpenter and a surgeon friend, the entirely new, promising and exciting audio tweaking realm of head shaping and ear angles. 
     My carpenter friend has been using a very sharp wood door planer to alter the size and shape of both sides of my head,  My surgeon friend has been using precisely positioned stitches to alter the angle of both my ears in small 5 degree increments.  We began the experiment with my ears in their natural position, measured at an angle of .000036457 degrees in relation to the sides of my head, and have currently progressed to the 90 degree angle position. 
     But I know what many readers are probably thinking and please don't worry, we meticulously recorded all head shape and ear angle measurements along with my subjective sq impressions after each progressive adjustment.
     I may not look so good, my kids are scared of me and my wife left me 2 weeks ago.  But I really think we just might be on the verge of discovering something that perhaps may be slightly significant.
     Oh, who am I kidding?  This whole process is pointless and extremely painful, something on my head's constantly either hurting or bleeding, I oddly look hideous and ridiculous simultaneously and we haven't discovered a gosh darn iota of useful information.
     I've wanted to call it quits for weeks now.  But my friends are so obsessed with getting results that they now have me tied up to a chair and refuse to let me go.  Can somebody please help me?......  Anybody?

Either that, or the ends are a thermal mass and the middle being the point furthest from being able to conduct heat away is where the heat builds up the most.

I knew this could be figured out. AND some take advantage of that VERY slight flaw. AND take it a step further.. Wrap with a tapered wire. That’s what got me..

What put me on to this was all the old bussman SBs, blew in the middle. I took me a while to figure that one...

THERE IS NO DIRECTION... LOL Never one end or the other, only the middle... The wrap failure would always be VERY close to the middle... WHY.. No direction in them, sound may not change, only the settling effect of a new fuse.

Put graphene paste on the fuse tips and CLEAN the fuse holder or swap it to a pure silver one. See what happens. Not plated, pure silver. It changes because of the BETTER conductive surfaces, on the fuse because of the paste, and holder because of the material it's made from, silver.

I've always thought that there's no way in hell that both ends of the melt wire are connected in the exact same manner to the insides of the end caps.

Because of assembly line automation, you'd have one kind of attachment point with the first end cap and as the final end cap is attached, another method. 

It would be secure but different. That could account for the diode effect.
Pure speculation but what the hey?

All the best,

Nuclear never seize, Graphene, diamond dust (2000), Rislone and, Everclear (180) something close. I break the graphene down and go from there. I dry my concoction with a low heat heat-gun. It stays tacky.
Never corrodes, I’ll tell you that.

BUT it can NEVER drip.. ok.. NEVER.. That is a no, no. Your mix is way off.

That concoction needs to set, and let the 180 evap, ay.. Then a heat gun.. LOW heat, (hair dryer).

To much rislone, or NNS. Its at least 50% graphene. Which is how many more times conductive than say, ANYthing else?

Diamond dust, a cutter, binder an seating compound, VERY little. SUPER insulative. Just the opposite of Graphene. It also causes the graphene to layer thicker, at least the thickness of the dust. You can get 1500 or 1000 too, for a thicker surface layer...

BE CAREFUL... All this stuff is pretty potent... 180.. proof. or poof, be careful..

Well first there's fuses made of beeswax or whatever, about a bazillion different types, some of which might really not be directional. So it makes it kinda hard to talk about anything like this without getting into specifics.  

Its actually pretty easy to think of a way a totally normal looking fuse can be made to sound a whole lot better. Everyone who has tried it knows a dab of TC will improve the sound of just about anything. Well, every SR fuse Blue or Orange, they all have a little circle with a dab of some gray gook on there- and instructions to NOT remove it! The same gray gook is also on the screw terminals of their Blue and Orange AC outlets. Hmmmm....

WHY do they sound different? It’s not magic. I’m a mechanic. It has to make sense to me.. If it doesn’t, I’ll figure out why.

I put this fuse in my Mac C20, it sounded different, I swapped direction and I lost a little twinkle. Swapped it back, I lost all the dynamics in the mids and highs, in a word, it became DULL. WHAT happened?

For that C20 to sound dull it has to set for a while, put in a NEW stock fuse, and turn it on. Two three hours to settle in and it sounds pretty good.

What could I have done? I did EXACTLY what the manufacture said NOT to do.. Yes I did, That’s me.. I wiped off the fuse and cleaned it all up, just like the direction said NOT TO... WHY? We’ll get there.

Is there less resistance at one end of the fuse wire inside? Is one end of the filament "tapered" to offer less resistance in one direction? Is the wire TAPERED that is wound around the filament to make a slow blow fuse?

IN CASE you missed it! The filament wire is TAPERED at one end. The wrap wire for a slow blow is tapered all the way to the end.. THEN it is wrapped around the inner filament, BOTH tapered.

Back to the top, I put graphene paste back on the new fuse after a GOOD LOOK!, Installed it in the original direction, listened, pulled the fuse, touched up the ends with paste and installed it sounded good.

NOT 3-4 hour wait.. It sounded GOOD, as good as it ever had, in 15 minutes.

Over the next two weeks, it just got better? WHY?

What is better? The best way to explain is. Sharper, cleaner, more dynamic. BETTER.. WHY? That part someone else can explain.
I haven’t figured that one out yet, or is the paste settling, causing this "better" sound? I think it is. Easy I’ll pull the fuse.. LOL
Not for a while anyways.. I’ll listen for a couple more weeks, before I confirm what I suspect.

THE MAGIC is not magic.

A silly ol, wore out mechanic, figured it out.. The direction mystery is solved..

The paste is super conductive and the filament(S) are tapered. There you have it.. Step up all you EEs Prof and smart guys, wHO EVA, as the English would say.
