Question about NAD C370 2-Channel Amplifier

Nad c370 problem....

Was listening to my nad pretty loud the other night, driving my old pair of kef q35.2s... but not as hard as i've driven them before. i was by the amp, about to change tracks when i heard a pop, which seemed to come from the amp, not the speakers, and i lost all bass... turned off and unplugged the amp, tried again, but to no avail...

trying to sort out what the problem is... usually i would have said the bass woofers are gone, but i've burned a few of them in my time and there was no smell this time and when i touch the woofers gently, they don't feel blown. also, the pop sound came (or i think came) from the amp...

i tried with headphones, it works fine..

i tried the "B" speaker outputs with the same speakers, there is nothing coming out of them... not even the treble. with the speakers plugged to "A" at least i am getting treble. which seemed weird and made me think the problem is amp related..

any suggestions on diagnosis and perhaps a fix would be appreciated..

thanks!

Hi arda5
Did you try swapping speaker connections left for right on the back of the amp to isolate the problem. If the fault stays with the speaker, then that is where your problem is. Try this and get back to me here with the results.

Check first if you got +68/-68V on amp module left and right on contact CZ302 and CZ402 pin 2 & 7. Often the -68V is missing. This is caused by faulty transistor Q713 in +68/-68V power supply. It's a 2SA872.

C370 faint crackling sound left channel


have you tried looking at your phono leads,turn volume down until it is low enough that you can still hear the music playing,give the phono leads a turn to see if its a loose connection.if not,try the right channel phono in the left channel to see if this fixes your problem.also you could do the same with your speaker leads and see if that solves the issue.maybe a bad connection is the cause?.it may also help to try and move your cd player away from your amplifier.it could also have been overdriven (played too loud for too long) on the night of the party,only you will know if this was the case or not.

Nad c370 keeps switching off


Check the speaker wiring for shorts, a common problem. If everything checks out there may be bad solder joints on the main board especially in the output stage, or there is a fault in one or more driver transistors.

Read page nine for some simple troubleshooting tips and see if that helps.

It *could* be a fuse but given you've owned it for a while and NAD amps often have capacitor issues in the power supply, chances are it needs some serious work by a good tech. Contact NAD directly and see what they recommend.

Since the problem seems to be sensitive to the volume level, I would be looking at the output wave form for any DC current. Although the protection circuit should detect any DC present, it is possible that some is leaking through. Also, verify that the speaker impedence is correct. If the amp is seeing too low an impedence load, it will work too hard causing excessive heat which will shutdown the unit as well.

Keep me posted.

This sounds like a problem with the protection circuit, and/or the speaker relays. More specifically, a capacitor within those circuits that is not behaving properly. I strongly suggest having it looked at ASAP.

HELP PLEASE. NAD 370 JUST DIED...


This could be as simple as a bad connection at the voltage regulator IC or blown output transistors. If you have a multimeter and some experience with electronics repair, this should be fairly straightforward.

Let me know and I'll try to walk you throught the repair.
