Isoclean fuses: definitely worth it

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.

Davemitchell: If I understand your comment (and I'm not altogether sure that I do) the fuse directionality issue has little to do with power. It is a matter of impedance.

For example, with capacitors constructed by rolling layers of film and foil together, if the lead attached to the outer foil is connected in the circuit to the lower impedance of the two possible connection points, it will be less susceptible to noise pickup.

If the fuses are indeed directional, it is likely due to some similar effect of their physical geometry.

However, I'm all for you selling the power company as much as you can manage. Go for it.

Since this is turning into a pissing match, I think I'll drop out. By the way, I don't participate in forums such as these so that I can be "educated" by those who think they know it all. I am here for sharing ideas peer to peer in a friendly manner.

I suppose I could have been to hasty. The digression on Galileo and falling objects was starting to sound a little like a "mine is bigger than yours" discussion. That gets old really fast. So does someone saying that a person is stupid, deaf, deluded if they say they hear something someone else disagrees with.
