Sheesh! There are only two issues I myself addressed:
1- The claim of fuse directionality in an AC circuit is, as Ralph Karsten keeps saying, simply impossible. Of that there can be no dispute. None.
2- In the case of, yes Joe, one amplifier being damaged by the Hi-Fi Tuning Fuse being used in a DC application, the great electronics designer (there, I said it) Roger Modjeski of Music Reference received a returned-for-repair RM9 power amplifier. Upon inspection, Roger discovered that all eight HFTF that had been installed in the amp had failed to blow when presented with a short from a bad power tube---the very job they are intended to perform. Further, Roger, upon inspecting the fuses, found them to not be of high breaking capacity design, a necessity in the application in which they were employed. In conversing with the designer of the fuse and it’s American distributor, he learned that neither was aware of that term. Therefore, Roger warned the owners of his amplifiers (which have fused power tubes) against installing the Hi-Fi Tuning Fuse in his amps. That’s all. What’s the f’in problem, Joe? I had no idea letting people know about a potential risk in installing that particular fuse in a DC application would so upset you. I’ll never mention it again.
Roger does, however, approve of the Littlefuse brand of fuses, and infact installs them in his amps. They DO possess high breaking capacity, and were designed by an engineer who DOES know what the term means, and it’s significance, importance, and necessity in a fuse.
I said nothing about the sonic benefits of audiophile fuses, nor would I. That’s a separate discussion of which I have no interest in joining.
