Question about NAD C542 CD Player

1 Answer

Nad plays for a minute or so...

After one minute aproximately, the left channel dies! A while after that there is noise and problems with both channels turning on and off...

The player is a NAD C542, and I am entirely responsible for the fault, as I have been tampering around with it, upgrading certain capacitors, etc. All well advised modifications according to certain internet forums where knowledgeable people share their modding experiences. I am not unqualified to make these modifications, I know how to solder and have a basic understanding about electronics and such, but I am not educated enough to diagnose exactly what might be causing this problem. What do you think, what does this sound like?

    Unless something is printed backwards on the surcuitboard that should be alright. Replaced almost all the new ones for cheapo ones for test purpuses today, but the problem is very persistant. I have a few more to pull out again, but if that doesen't work, what would you say would be the second step?

First thing to do is to check all your new caps and their polarities.

    Maybe, you have didstubed soldering on D/A converter IC, normally it is surface mounted with around 100 pins.

    Before that, check soldering on sound preamp IC's two small ones close to audio out sockets.

Teac A R300 right speaker has s badly distorted sound after 20 minutes. When I turn it off nad turn it on again, Same problem after 20 minutes. Left channel working perfect.

Have you changed the speakers to see if it is a driver, or amplifier, issue? If it follows the speaker, get it reconed. If it follows the channel, look into that channel.

NAD 272 Channel drop out

well..this is one for the books. Can you tell me what the ratings are between the 252 and the 752 impedance matching wise? even though it might work sometimes, impedance matching can wreak havoc between mismatched amps.

what are you driving from the 752 into the 252?

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 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.

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!

My NAD C320 outputs a very low sound volume

Hi there I have a C340 that has similar problem, you must have bought this from ebay, lol.

Nad made a mistake on the C range, the pre - power link can be shorted out. if the pre is shorted out it takes out the pre amplifier stage, I have managed to get the right channel working, I will keep you informed what is the cause of the left channel. I have replaced the pre-amp IC and a couple of Jfets and transistors. Once I have repaired the Amp I could repaire yours if you like???

Nad 310 blows fuse in left channel at turn on.

Hi, Unfortunately, this means that the output transistors on the left channel have blown. I've rebuilt a couple 310s, and I own one myself, so this isn't the first time I've seen it. The chassis doesn't ventilate the left channel as well as it does the right, so it tends to die sooner.
If you can do this yourself, it will not be terribly expensive, but the main output transistor is a MOSFET, which means you'll have to be very careful about static, and you'll have to find a substitute for it as well, as it is no longer available.
I strongly recommend replacing the small electrolytic caps in the amp too. By now heat and age will have taken their toll on them. In my 310, replacing them wasn't an option to get it to behave well.

Drop out of left channel, Adcom GFA5802

It sounds as if there is a broken solder joint somewhere that slowly opens up with heat. The other possibility is that an input or driver transistor is dying. Since the whole channel is dying, I would guess the broken joint and/or dying transistor are near the very input of the channel.
A tech can very easily find the spot by playing the amp until it starts to die, then spraying small bursts of freeze spray, one component or area at a time, until the amp suddenly comes back to life.
