I bought an SR purple fuse for my PST from https://www.vhaudio.com/. Chris VenHaus, the owner, wrote this to me in an email:
āNote that the 250V they cite is a voltage rating that is MINIMUM rating the fuse needs to be rated for, and is the max voltage the fuse can successfully ābreakā (and keep broken) AFTER the fuse has already blown. All my fuses are 400V and higher, so even saferā¦ā
By the way Chris is very helpful and a pleasure to deal with.
Hope that helps.
I have a P15, but am forgetting which value Orange I put in a year ago. One thing for sure: the past few SR fuse models have not been built to industry standards (UL), and as a result many users have experienced blown fuses at component specs. Unless a component is tightly specād, and most arenāt by 2-3x or more, itās become common to go up an amperage level or 25% (e.g., 2A to 3.15A). Audio Magic and most (or all) others are built to proper standards.
I pur a Purple fuse in my P15 about three weeks ago, replacing a Blue fuse.
It has been a great improvement. As a result I have replaced Audio Magic Super fuses in my Decware ZTPRE and now my Decware SE84UFO3 Monoblocks with the Anniversary mods. This was a different type of improvement, but I still like the sound very much and it has a synergy with the fuse in the P15. I have ordered one final purple fuse to replace an Audio Magic Super in my Decware ZROCK2. . . then Iāll have a āfull Purple loom.ā Looking forward to the day all of these are seasoned in placeāI imagine a great system sound.
It is interesting that Purple made a bigger difference in my P15 than in my BHK pre. I do not know if that was because my brain was adjusted to the sound of Purple, or because it was the power generator benefits more than the pre.
My thinking is that since the regenerator feeds all other gear
in the systemā¦the key place for installing would be the regenerator.
If you install an upgraded fuse into a pre or amp without first
installing one in the regeneratorā¦the results will not be anywhere near
as notableā¦
