Hello,

My NAD C-370 integrated power amp all of the sudden has decided not to power up. No lights, nothing. I opened the case and there is a plastic cover labeled FUSE. Of course it doesn't seem to want to come off very easliy, but I'm guessing it's supposed to.

My questions are: Does anybody have any experience with this, or have any other ideas of what I can try to get the NAD up and running? Should I continue and pop off the FUSE cover and hope Radio Shack has a replacemeant? Thanks!

Yes, check the fuse. Don't expect it to be the problem. It's not all THAT common for fuses to blow without there being some other problem.

Take care to get an identical fuse. If for example it is a slow-blow or a fast blow fuse you must replace it with the same type, not just the same amperage and voltage rating. Amperage is actually key, as it is current that blows the fuse. So it is ok to replace with a higher voltage fuse but not a higher amperage rated fuse.

But I agree with the other poster--it is almost never the fuse, but it is the cheapest immediate repair possibility.

Thanks for the responses. I did try and check the fuse. I also happend to break the plastic housing for the fuse while trying to get at it. Oops! :( Then on top of that NAD put a fuse in there that is opaque so you can't tell if it's cooked or not. I've never seen that. Of course Radio shack doesn't carry an exact match for the fuse and at this point I think I've done enough damage already so I'll just make the call and have a shop take a look at it. :eek:

You can take the fuse out and measure it with an ohmmeter, use the continuity test (it should beep), or just look for < 1 ohm on a regular resistance scale. It also doesn't matter if you broke the housing, as long as it's still secured to the board, and nothing metal will touch the metal parts inside. But a little tape fixes that if need be...

However, the shop is probably a good idea, it's probably not the fuse. But if you've got an ohmmeter, it doesn't hurt to try it.
