Periodic replacement of Audio Grade Fuses?

I just installed 2 Isoclean Power 24k gold fuses in a pair of Quicksilver mono amps. I am very happy with the results.

The card that came with the fuses stated "Fuses always carry high electric current thereby easily causing metal fatigue. This would then adversely alter the conductivity behavior of the fuse element and hence the performance of the equipment. Under normal conditions, Audio Grade Fuses should be replaced from every 6 to 12 months the longest."

I have had regular Buss fuses in my equipment for many years without need for replacement. It would seem that if the fuse element fatigues enough, that the fuse would blow or fail. At $50 a pop, this would add up. Seems that regular replacement is sales hype and would only benefit the fuse manufacturer. I am not electronically tech savvy.

Any thoughts on this?
Thanks.

Maximum Capacity is a RATING not a Challenge

The MOV’s that protect our equipment wear out gradually over time and continual use, yet continue to function in their capacity ... why not fuses

They are both in the AC protection business and function in a similar fashion up to their “Maximum Ratings”

I suspect the difference is Fuses have a much long Half Life than MOV’s do ... similar to the giant stars burning out much faster than the smaller ones

Hot one today ha
