Installed Yellow into my Lampi Pacific yesterday and have had two days on it.  I did try to paste the 1260 to the end caps but it was almost impossible to install without losing it all on my fingers.  I still have 3 other components to install the yellow fuse to.  

Question on directionality...what exactly will you hear if you install the fuse the wrong way?  I have had the SR Black, Blue and Orange.  My assumption has been as you look at the back of the amp, I place the fuse going left to right with the writing on the fuse.  Either i have guessed right everytime or that is the correct way to install. 

I am not ready to provide my analysis on the yellow in my Lampi  I am going through a process of picking music that I know I can hear sonic differences. One example would by Nils Lofgren Band Live -Girl in Motion song.  The guitar solos are really good.  


Fuses suck period
I am glad my Bricasti dac-Streamer don’t use them ,one less bottle neck


Yes so does this "snake oil" talk about them here.
And btw they are not a "bottle neck" for the AC supply. For them to be that they need to be far more "resistive" than the "minuscule couple of milliohms" resistance they measure.
There more resistance in all the ac switches you have in series from the mains box switches to the wall socket switches to the equipment mains switches, than that 1/2" long piece of fuse wire in a fuse.

To those "non technical" members that are interested, do not listen to fusers, listen to the techs of this industry that design the audio products you have.
AND YOU WON"T SEE THEM ON THREADS LIKE THIS AGREEING WITH WHAT THESE FUSERS SAY IT WILL DO FOR THE SOUND, EVER!!! LET ALONE BEING DIRECTIONAL!!!!!
Just clean and tighten your fuse holder and re-new your fuse (if old) with a good quality 50cent Bussman, Littlefuse or similar.
As with "many switch-on surges" they do deteriorate, bend, stretch and get crusty with electrolysis formations on their fusible wire elements before they give out, as these pics show of a fuse wire element ageing over time show. https://ibb.co/9NbTwqK
(even the $$$ boutique ones will age just as much also)
Cheers to all "non fusers" George
The fuse is NOT there to protect the component! The fuse is there to protect the HOUSE!

This is a false premise.

The fuse in the device stops it from drawing too much current and destroying its components.

It is the circuit breaker in the power board that does not allow the wiring in the walls to exceed its capacity and consequently protects the house. It also detects earth leakage and protects humans.
