Isoclean fuses: definitely worth it

Jadem6, you read the thread wrong in my opinion. There is no question that there are multiple replacement fuses that are superior to what you normally get in electronic. I have replaced fuses in 9 components thus far. Some are dramatically improved; others are less improved.

Fuse direction with all fuses often makes a great difference. IsoClean marks their fuses direction and thus far I have found them right.

All fuses get brittle with turn on surge. I have never tried replacing fuses just to see whether or not I got a sonic improvement doing so. Your expeience with a fuse lasting 35 years on your tuner may not invalidate this as you have not replace it to see whether sonics improve.

I do not know whether the IsoClean comments have validity or not, but I have much experience to suggest that their fuses offer a great improvement. I have been using some of their fuses for well over a year now with no problems. I guess I could try replacing them to see whether sonics improve, but I probably will not. I am still struggling with which products best clean cds and sacds. I have resolved to my satisfaction what is the best vinyl cleaner.

Interestingl little thread. Let me see if I can stir the pot a little.

If I need to replace a fuse every 6 months, what about the rest of the power supply? For that matter, maybe I need to replace my whole stereo every 6 months.

As to directionality, even a piece of wire will exhibit some amount of inductance, capactance and resistance. Lots of capacitors are constructed by rolling an inner and outer foil together with an insulator like polypropalene in between. There will be a lead attached to each foil. Depending on whether the inner or outer foil lead is connected to the higher or lower impedance point in the circuit will affect the capacitors tendancy to pick up noise from radiated fields around it.

So what am I driving at? It is possible that the construction geometry of the fuse makes it more susceptable to noise pickup in one direction than in the other and this will be dependant on the SPECIFIC circuit it is used in. Meaning that it is possible that one direction will be preferable to the other and that this will vary from one piece of equipment to another.

OTOH maybe it's all BS.

read above that there is slow and fast blow fuses. is it not functioning the same? how to know if you amp take slow or fast blow one? my amc do not mention any.

Willster, I have thus far ignored the notion of replacing the fuses each six months. I did replace one once and heard no difference. This would, of course, increase sales.

It is certainly possible the construction geometry may account for the directionality of fuses. I have many times identified what I am told is the proper direction for using IsoClean fuses, listened, and then reverse the direction and listened again. Each time the right direction sounded better. I have tried Hi-Fi Tuning fuses and found they also have direction but it is not consistent with any external indication on their fuses, such as printing.

There is one quick way to decide whether this should be of any concern to you, try reversing several of your fuses, one at a time. If you hear nothing,...

Milen007, I have only found amp manufacturers to strongly suggest using slow blow fuses as they have a strong turnon surge that might overheat a fast blow fuse and blow it.

Bob P. If power doesn't flow in a particular direction then I should have no problem telling the Electric company that I will no longer be paying my bill. As a matter of fact, I think I'll start charging them!
