Interesting post about aftermarket fuses this week from a designer-manufacturer of well-regarded DACs, amplifiers, and other electronics,
"Depending the type of product we use transformers in a range between 15 and 30 VA. It means that the primary windings are as thin as monkey hair and will have a length of approx. 100 meters. The resistance of this primary copper winding is about 60-90 Ohms so what will be the effect of one centimeter of fuse wire compared to the primary copper wire."
I suspect this viewpoint may be considered too simplistic and unenlightened by those savvy folks who believe in the mystical effects of that "one centimeter of fuse wire." OTOH, aftermarket fuse manufacturers are probably already thinking about the potential profit on fuses made from beeswax, monkey hair, unobtainiam end caps, and (pick your color) paint.
