What direction should Hi Fi tune fuse be installed

I just looked inside to see which side has the wires to the transformer and which appear to have nothing. keith

Put all of the fuses in. Then start listening to the music. Swap direction of the first fuse and listen again. Choose the direction that sounds best. Now move onto the second fuse and do the same. Finish with the third fuse in the same way. You should then have the best sound at the end and the fuses orientated the right way (assuming you can pick fuse direction on your system). I find it quite noticeable with fuse direction. I have a combination of Hi-Fi Silver Star fuses and Furutech fuses.

For a long time Hi-Fi Tuning claimed there was no direction, but I always found there was, but it was predictable judging this from the printing on their fuses. With IsoCleans I have always found the arrow going with the hot side input is the best sounding, so I would confirm the current flow direction is the right direction for the arrow.

I should say also that when Synergistic Research tunnels fuses they do so in the direction of current flow. This greatly improves the sound as does painting the glass with AVM paint.

Not having experimented with it, I am not in a position to take a position on fuse orientation, but fwiw it should be pointed out that ac current does not flow in one direction, it oscillates back and forth in both directions.

One direction of ac goes through the transformer windings as they are drawn. Also one direction of ac is at the live end of the switch. All that I can say is that whatever the explanation, the directions of fuses sound different.
