why not send it to Naim for a factory service?
Fantastic! How do you change an LED? Send it to Naim for a service! :0)
Rico, Naim dont pay you at all do they? ;0)
Actually Jeremy, Naim are great about this sort of thing and quite happy to help you do such minor jobs yourself. If you give them a call theyll probably send you all the bits you need, instructions on what to do and I doubt theyll charge you much at all. Swapping an LED is simple, you can buy packets of the things in Radio Shack.
Another thing you can do is change the hi-caps to look like olive style ones. More expensive and more work obviously but nice if you like the newer look. The black front on the old kit is just a plastic sticker which you can peal off, the olive front sticks on it its place. The new knob replaces the old one and if you turn the case around so that the chrome edge is at the back youve got a black edge at the front! The newer cases are a slightly different colour, mid-sheen dark grey instead of gloss black, but its not obvious at all.
The biggest problem is the NADI board, the little LED board that lights up the Naim logo. It is powered by the wires that supply old LED but it needs more power so you need to add a resistor piggyback to the one for the old LED. Thats not the problem though. The hard bit is the fact that there is no cut-out in the front plate for the NADI board, youd have to cut one yourself or have no display illumination. Not an insurmountable problem if you dont mind getting in about it :0)
Incidentally, Les at Avondale can send you new caps if you want to re-cap the things. He charges about half what Naim charge for a pair, I did it not that long ago.
