Inrush currents from moment of switch on, can cause a fuse to be weakened by many said inrush turn on’s, to a point of blowing one day, here's a visual proof. https://i.stack.imgur.com/0uqWX.jpg Cheers George |
I have no qualms with the images of the fuse that George posted. I suppose they are of the same one as it ages. That is the type of fuse I avoid using: a bog standard one, made to a price point. Again, 😩, a better made fuse can be had if you're willing to pony up for it and it doesn't need to break the bank. All the best, Nonoise |
That is the type of fuse I avoid using:All correctly implemented fuses are close to their blow point in normal operation, as if anything out of the ordinary should draw more current that's not normal it should blow to protect and keep the circuitry/pcb's from being fried to an absolute minimum. The fuse I linked to, shows what many switch on surges can do to ANY properly implemented fuse. As current draw at "switch on" is when an ac mains fuse is taxed the most, and when weakened ones, that have seen many switch on surges can blow, even though there's nothing wrong elsewhere.

Whoa! What? Looks like I t’s still the same tired Strawman argument, that "properly implemented" or properly working fuses are all that’s needed. I mean unless you’ve completely given up and no longer wish to chase the dragon and pursue the whole sound quality thing. It doesn’t take a rocket scientist to understand that the purity of the metals of the end caps and fuse wire as well as attention vibration and RFI, cryogenics, affect fuse performance. Just like cables. I don’t even have to utter that forbidden word, you know, the one that sets naysayers’ hair ablaze. 🔥 🔥 🔥 |
