Question about NAD T163 Amplifier

2 Answers

Pop in left channel

I had to replace my NAD T193 amplifier, and when reconnecting it to the T163 preamp I now get a loud pop in the left channel, which breaks the circuit for the channel in the amp. Once it resets, however, I get normal sound. It happens if I turn the preamp on before the amp, and when I turn the preamp off before turning off the amp. It happens when I change functions. It happens when I pull the left channel plug (from preamp to amp). I've tested the amp, and it's definitely not the problem. I've disconnected everything from the preamp, and it still does it. However, it does NOT do it through headphones. Anyone have a clue?

Hi guys. Having a problem with my NAD T163 Surround Sound Decoder. Popping in front left and right speakers when changing audio selection. Works well other than that. Please give me some suggestions w

Could be DC voltage on the speaker output line, but this will generally keep your receiver audio output turned off completely. Could be a bad muting transistor or microprocessor IC(computer within your NAD). If you are interested in having your NAD repaired, please visit my website at may contact me there. Thank you..

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.

Cracking noise nad c340

Sometimes you can find the faulty part by touching the parts inside the amp. Only touch the plastic parts not any metal parts! As it is on one channel you have a good channel to compare the bad. Often small transitors can become noisy so start with them!

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

Nad c370 problem....

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.

NAD C740 no longer reproducing music through loudspeakers

what was your amp? ic or transistorized? the output transistor of your amp may be opened, mostly it will short but because u still hear sound, maybe open and only the driver transistor are working. replacing output transistor or IC could solve the problem.
