HiFi Tuning fuses direction

You probably need an Electric Engineer or call GamuT to find the correct answer on this one. The arrow is pointing where the signal is flowing, very much like Interconnect Cables. I would place the fuses pointing from the power cord out(or in some cases which fuse's end is nearer to the power cord) and the arrow should be pointing >>> out from there.

Does it matter on the AC power side?

Magfan, what do you really mean here? you mean if there's a different if you placed the fuses the other way instead? I guess you just reverse the signal flow, not what it suppose to be.

AC current flows in both directions.

To some people it does.

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 The crossover jumpers have been replaced by copper....instead of the chrome plated steel (!)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.

Maybe think of potential instead of direction. Potential is higher at the source than nearer the load weather AC or DC unless there is absolutely no resistance in the circuit.
