They sure don't make amps like they used to.

Is the noise there on all inputs?
Is it there on both A & B speaker outputs?

These units are known for having bad solder connections so does tapping on it or giving it a whack change anything? And dont be afraid to give it a fairly solid whack.

I wasnt 100% certain the speakers were eliminated. Logically, I didnt see how they could be but then again, i tend to get stuck with unordinary lol.

The noise is always on on channels. I switched the kimber cable and even had them professionally soldered with connectors, no difference there.

The noise just happens, low or medium volume, no difference. It is horribly annoying when out of the blue it happens.

It happens on all inputs, I connected through composite to tv, dvd, cd, etc. No difference. Only Speaker A outputs. I believe back them IT Electronics in Burnaby resoldered the joints

In retrospect, people warned me after I bought the unit of NAD. Back then, the internet wasn't as prevalent as it is now so researching the amp et al wasnt as easy at is now.

@pw599, @scarybob, back then I didnt know about being stuck with a lemon and three warranty repairs and still no resolution. I really beat myself up at times but now I know more than I did back then. However, the cost was huge for that entire system. Now, it's just sitting in storage and I listen to mediocre playback of music #sigh

"Only Speaker A outputs. I believe back them IT Electronics in Burnaby resoldered the joints"

Does that mean the noise isnt there when using the B speaker outputs?
If thats true, things got alot easier.

Dont beat yourself up about it at all. You've got a fantastic piece there and now it's going to be called vintage.
That series of NAD was finicky, I know, I have one and I use it. But issues can always be overcome.

Get it out of storage and enjoy it, once it gets fixed of course.
We'll try to help with that here.

Get back to us here when you have it hooked up and ready to go.
One of the 1st tests you can do is get it going with the cover off, and tap lightly on the speaker relays while running at low volume. Obviously be careful while the cover is off but dont get too panicky, nothing is going to jump out and bite you, just dont be sticking fingers in and around the ac input circuit. Or anywhere else for that matter. Take a light plastic handled or all plastic screwdriver and locate and tap the relays, see what happens.

I'm sure you know that can be run as a separate preamp or power amp depending on the jumpers at the back. So if nothing else you can maybe still use one or the other separately. It does very well as either and you'd only need to add a power amp, or preamp.

I had a similar situation with a Harmon Kardon amp. It started emitting a most excruciating noise after about a month. Moving it (or flexing) would fix the problem for about a month. So, of course, the repair shop never found anything wrong. (The repair shop manager was an a-hole as well but that's a different story.) Placing something under the right front leg of the amp also fixed it but that looked really goofy. I ended up trading it in under warranty. (No three strike rule then either.) In retrospect, I should have taken it to another shop. I've never had much luck with in-store repair departments. Find a good independent instead.
