Fuses that matter.

I have tried six different fuses, including some that were claimed to not be directional. I have long used the IsoClean fuses as the best I have heard. No longer! I just got two 10 amp slow-blows WiFi Tuning Supreme fuses that really cost too much but do make a major difference in my sound. I still don't understand how a fuse or its direction can alter sound reproduction for the better, but they do and the Supreme is indeed! I hear more detail in the recordings giving me a more holographic image. I also hear more of the top and bottom ends. If only you could buy them for a couple of bucks each.

Liquids expand when heat is applied, and liquids will not compress(had to go somewhere). Any overload, that heats a fuse's element slowly, will also heat the liquid. A rapidly blown fuse element; not quite as much.

Roxy, I wouldn't touch your comment with a ten inch pole.

Rodman, I have a few of these fuses. They are not completely filled with the polymer. Maybe about 75-80%. I don't know what the coefficient of thermal expansion is for this particular polymer, but it would take an enormous amount of heat to pressurize the fuse to the point of breaking the glass or pushing off the end cap. This particular fuse is a 800 milliamp fast blow fuse. If the OP's Sony drew enough current to do this, he's got more to worry about than a non conductive polymer on his PC board.

Mr B- I wonder what the odds are of one of these fuses getting off the line completely filled. It would then take very little expansion, to result in leakage. Hydraulic pressure HAS to go somewhere. Perhaps combined with a loose cap/poor seal? Manufacturing anything, without some kind of failure rate(however slight), is next to impossible. I just don't believe that it's leaking when it blew, was simply coincidental.

Rodman, I agree that something must have gone wrong. The residual gas in the fuse could have pressurized sufficiently to crack an existing flaw in the glass I suppose.

It would be nice for Mr S to return the fuse to Jerry, for analysis.
