No, it’s a very specific fuse you need. A Naim dealer can supply. It’s a T fuse and rating and type, even the make is really critical. Get a bunch of them, just in case. Only ever use the exact rating and type of fuse - it’s critical for safe operation.
Not so much the XPS, but the XPS2 can be more prone than usual. I guess it was down to the particular transformer and regulations. Upping the fuse rating meant it wouldn’t pass regs and a value in between didn’t really exist, so it had to be a 2.5A T fuse which meant it was right on the edge at switch-on when you have the greatest in-rush of current.
partly because lots of people plug things in with 13a fuses, which is far too much current for many devices - the only way to ensure the right rating is to either permanently attach the power lead with an integrated plug at the end, or to have internal fusing. It’s to protect the less aware from themselves…
Well of course he won’t see an XPS back after this, because the fuse has lost its purpose. Question is if there is any electrical issue in the XPS and the apartment burns down, does he pay for the damage? Because your insurance will not.
