PS Audio PWD MKII HiFi Tuning fuse direction


What is the correct / preferrable HiFi Tuning Supreme fuse direction in a PS Audio PWD MKII? I heard arrow pointing from back to front.

Fuse is not easily accessible to roll so just want to confirm.

Thanks!

I use these fuses to excellent effect in my vintage Sansui tuners and directionality makes an obvious difference. Why would it make a difference on e.g., interconnects but not fuses?

Because interconnects sit in a DC circuit, where current flows in one direction. The fuse on the PWD sits in an AC circuit meaning the polarity switches 60x per second. How can directionality of a fuse make a difference when the direction of the current flowing through that fuse changes direction 60x per second?
It doesn't make a difference in cables or fuses. Electrons do not care what arrow direction a manufacturer may put on a label.
I have hard time rationalizing directionality of cables and fuses, but in a DC circuit we can at least entertain the idea it makes a difference. In an AC circuit in my view it is categorically impossible there is a difference.
