Only if you replace the pot with two resistors of equal value. Both need to be also equal to 1/2 the value of the pot. Then at the point the 2 res tie together -- Tie that point to the middle lead location and the other leads to the other points where the pot was connected. Use 1/2 watt or 1 watt res.

NAD C370 distortion


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.

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.

Myc370amp turns its self about 15seconds after turn on


Replace 3 capacitors on the protect printboard. (located near the outpt terminals) 50V electrolyt: 4,7uF, 47uf and 10uF. And move the big diode to the back of the printboard (the heat from the diode dries out the capacitors)

Work in 9/10 times ;)

NAD C270 amp won't switch from red power/protection to green.


The AH may denote "slo-blo" style as opposed to Fast-acting
A fast-acting fuse will look like a single strand of wire ( maybe wiggly looking) ..A Slo-blo will have an element in it and a spring

No power at all on NAD C370


User manual here

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.

Sounds like you have lost the power amp transistor(s) or IC for this channel.
