what do you have to lose?Credibility and money, just change your tired old 10c fuse for the same new one, as they do deteriorate over time with on/off surges, as shown in the pic, even the boutique ones, and clean your fuse clamps.
"Fuse aging by switching loads
The fuse wire gets hot and expands when current flows. At high temperatures, oxidation may happen, which weakens the wire mechanically, and may be electrically, too. Switching on/off a load means the wire is bent each time."
