HiFI Fuses ?

Tbg - a well reasoned correction of previous misinformation! Good job...

Which misinformation? So AC current does not change direction? Ground and neutral are not necessarily the same. Even if the 'directional' fuse were a partial diode, it would act as such in either direction installed since the current reverses as many times as the frequency indicates. Grounding doesn't come into play here.
The last time that I looked at the amplifier output connections to the speaker I saw the voltage swing from positive to negative, therefore the current varying as such. When directionality is shown on cables it is to indicate where the connection for the shield should be, usually at the preamp, not the direction of the current or signal.

I'm with Bob P. on this one. I've yet to read a reasonable explanation for a fuses directional aspect, within any part of an audio cicuit. I'm open to explanations, though.

inpep---, so the neutral does no duty relative to serving as a ground often for the circuit and the chassis? Also stop switching the discussion to speaker-wires. They have nothing to do with this thread.

All that I can say to both you and Metro is that you should listen first and consider afterwards whether your understanding of circuit design can cope with what you hear. I know you hold desperately to the predilection that fuse direction cannot matter and want no evidence that you are wrong.

TBG, I need more than apocrophal evidence that direction matters, since I don't even detect any difference in even 'ordinary' fuses let alone 'directional' ones.
By the way, what is directional about these fuses, besides the arrow (I presume) marked on them?
As for speaker wires not having anything to do with this, - well, I use them as an illustration of why directionality has no effect on circuits or wiring when they deal with AC currents, grounded or not. Perhaps you object to my use of that example because you have no evidence that I am incorrect about that.
Remember that a fuse is just a short piece of wire with the added property of melting at a given temperature, the heat being caused by the current through the wire, changing direction continuously.
