HiFi Tuning fuses direction

The arrow is pointing where the signal is flowing<<

AC current flows in both directions.

Does it matter on the AC power side?<<

To some people it does.

I will place the fuses like interconect,pointing the arrow to the left-in >>

What do I mean?
Well, AC power before the transformer, even, is symmetric and at a very highly controlled 60hz.
I simply can't imagine a fuse having an audible effect based on orientation in this application.

Now, my panels have fuses and they are goners. The crossover jumpers have been replaced by copper....instead of the chrome plated steel (!) which also helped.

I guess I just have trouble with fuse polarity on the power line side of the AC transformer.

Try it in both directions and let your ears be the judge.
If you can hear a difference, then leave them in the direction that sounds the best.
If you can't, then it wont matter.
