Vibration control inside a cabinet

AC alternates…that's why it's called AC, and another reason fuses aren't, or simply can't be, directional.

Wolfie, can I suggest you march yourself right down to that audio engineering school you went to, assuming you did go to one, and demand your money back? On a related subject have you given any consideration to some sort of reading comprehension refresher course.

George, I would give you the same advice I gave Wolfie but alas, I fear, you know, judging by your own words, you don’t have a school you can march yourself down to and ask for your money back.

Geoff,
I know you will correct me, but your argument is based on the fact that in the process of pulling the wire through the die the crystals get damaged, that is, the damage forms a directional bias.  The passage of protons and electrons are impacted as they flow, if AC, in both directions. So if the AC current flows in both directions, how can it matter which direction of the bias wire (fuse) you place it?
