I just received an SR Orange fuse to try in the preamp. The directions say that current should flow from left to right as one reads the letters ‘SR’ that are printed on the fuse in normal orientation. I assume – but do not know – that current flows from the back of the fuse holder, next to the outside of the chassis, toward the interior. Is that right? Would that also be the case for other PSA products (DMP, BHK 250 amp)?
Fuse skeptics, please ignore this. I don’t know why fuses matter or why they should be directional. I’m just trying to follow directions to get the best outcome possible (and I am open to the idea that I won’t hear much if any difference). I’ll report back on what I hear.
