Nad C320 right channel stops working then comes back again
Hello, I've had the amp for a few months, worked fine until now the right channel stops working after a few minutes. if i turn it off and on again, both channels will work for a little while, but then the right one dies. I tought it was somehting with the cables, checked them and they seem ok. also, the same thing happens if i put headphones into it, so i'm guessing it's a sort of an "input" problem.

This sounds like the "pre-amp" section is cutting out or there is some interruption in the signal path. A few things to try:
1) With the unit off, try "working" the volume,balance and tone controls. This means, turn them up and down a number of times to clear any debris that may be in the controls themselves.
2) Work the input selector switch the same way if it is a rotary switch.
3) Try turning on/off the tape monitor switch a few times.
4) Keep track of whether this problem is sensitive to heat. Does teh channel shut down more quickly once the unit has been on for a while?
Lastly, if you can solder, look for any solder joint that appears grainy or has rings and resolder it.
Update this with your results and we'll continue on...
