N272 - XPS dead

See the FAQ.

Again...

Might be a good time to go and chop some more wood for the barn Richard. and then come back to this thread after a stiff drink 

I'm trying James.  I'm trying...

You’re in the right place then. 

its a bit early for that stiff drink, another option is to print out the forum members avatars and stick them on the end of the logs this should help with the healing process after applying the axe

Last time this happened to me my dealer reminded me that the fuse is directional - I think with the kite mark facing upwards. Not that I've experimented though!

I've always wondered about the concept of cable/fuse directionality when they carry an AC signal (?)

I believe it has to do with the direction the wire is drawn through the die and how the electrons in the metal subsequently align, so it may be a theoretical matter. Whether or not there is an detectable SQ difference is another argument, but I'd just go with prevailing convention.

Seems my xps has done the same. At least I hope that's all it is. How common is this for an xps? Should I expect this to happen often?

It depends. If you switch it on and off a lot rather than keep it on all the time then you should perhaps expect it as a possibility every now and then. However, on my two XPS2 and XPS DR units it only ever happened once over many years use.

Good to know. I do keep my gear powered on but I had to move some things around and the powerlines were being a bit finicky so I think that's what caused the issue. Hoping that's what it is. 

I have found that if you disconnect the XPS from the 272 too soon after turning the XPS off, it can blow the fuse. Maybe it’s because the caps are still discharging, or maybe not. Anyway, leaving it a couple of minutes avoids the problem. 

Yup, a loose and arcing Powerline can easily blow the fuse.

Naim is not a plug&play hobby. The customer is asked to pay a lot because he has a lot of responsibility in the correct setting for the system's full and consistent working...

I tried other, more user friendly brands, but I got bored.

IN GENERAL Heavy duty mains cables will put mechanical stress in the male socket  and could cause arcing if it is not secure

Good news it was just a blown fuse. All is well know plus being sure my powerlines are properly attached. Thanks for the help. Now to order a spare fuse from my dealer.
