Replacement Fuse's - What are my options ????

The listening test will verify the proper direction.

With any fuse, even one that is 10 years old.

"In all my experience with such fuse holders the arrow should go from left to right when you are looking at the fuseholder. " - that all depends on whether you're looking at the fuseholder from the right side or the left side :-)

GK

TBG, just because there is "continuity", as you put it, doesn't imply that the current flows in only one direction. AC current, by definition, alternates in its direction and voltage, 60 times a second in North America and 50 times a second in most of the rest of the world.
Now fuses installed on the DC voltage rails might have directionality, but I have my doubts, no matter what the fuse dealers say.
With respect, Bob P.

Bob, I am only identifying the hot wire to the transformers.

All that I can say is that I have repeatedly heard the impact of the proper direction for fuses. IsoClean marks theirs, and I have always found they are right. Only you can be the judge, of course. Try switching the direction of the fuse in your line stage and see what you hear.

As far as I know only IsoClean claims fuse directionality, but many have found it on other fuses.

I don't think anybody mentioned the Furutech fuses which I just stumbled across. These come with a pure silver conductor, rodium plating, and cryo-treated to boot!

I've owned the excellent IsoClean fuses, I'd like to try the hifi.com fuses, but I think I'd have to go with these next.

Stehno, damn you! I had just dismissed the Hifi fuses given the comments in the review I posted. These sound like exactly what I have sought. Do you know what they cost?
