NAD S200 one channel is not working
You have a fault in the power amp. Identify the faulty channel by following the input leads. As, a stereo amp is basically two mono amps put together. You can compare the bad channel with the good one. First thing to do is a visual look around. If you see something odd looking in one channel and it's the faulty one, compared with the good channel, you might have found the cause. Look at the devices or device on the heatsink especially. If nothing stands out, the next thing to do is test the channels. You can do this in two ways. First, by touching the parts on each channel (with power on) with an insulated screwdriver. If you get a buzz in one channel and nothing in the bad one, in the same places of course! You might have located the faulty device. You can do the same with a volt meter. The readings should be the same in each channel. Work forward from the end of the preamp stage. Don't bother with the power supply parts, as they are common to both channels. By the way, don't short anything!

Nad 326bee popping sound?
Does it occur on both channels at the same time, (power supply) or independant channels, (coupling capacitor).

NAD T752
Hi,
When powering up,
It could be entering protect mode because it has no speakers wired to it, have you tried connecting to all 6 speaker - out connections. Often, if an amp can't detect a load on all 6 channels it won't work. Also, have you checked the thermal fuses? a blown fuse could cause this problem.

Nad t753 volume control knob doesnt work
I'm going to assume that you mean it jumps around, volume up/down by itself? If so, you have a bad rotary encoder. If you are interested in having your NAD repaired, please visit my website at audioserviceclinic.com. You may contact me there. Thank you.
