@bdp24 - As I’ve stated before, numerous times, IF that article is correct, WHERE’S THE EVIDENCE? That ONE incident can’t be the only one, CAN IT? You can take his word for it, but- I’ve personally been using HIFI Tuning fuses in my tubed amp, DC circuits, for better than 12 years now, without a problem, EXCEPT when the occasional tube went South, and the fuse DID IT’S JOB. Far as I'm concerned, without corroboration, that article is, "rhetorical".
