Hi davidfluff

You need to check around the output stages for dry solder joints. Then also replace the BD139 bias control transistor on the heatsink with a 2sd669. The BD139 can be prone to thermal runaway in this circuit Then setup the bias current and DC offset in the output stage. If you are not familiar with the things that I have just told you, you need to contact a technician, if you mention these things to him, then you stand a fair chance of getting it sorted out.

I am more than happy to answer any other questions you may have about it, please get back to me here, or use the ASK function to go straight to me :) If you are still unsure, have problems, or we need to look at the situation more deeply, then before you give a rating for this advice, hit the ASK button Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you.

NAD 3150 cuts out


Hello. Slapping and it working is a tail sign that there is a loose connection, bad solder point, loose wire. When a circuit board gets hot, solder joints separate and an opening occurs in the circuit. Open it up and get a visual. Look for cold solder joint, make sure all the connectors are secure. Good Luck

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?

Nad c320bee keep over heating


Hello
Disconnect all speakers and switch ON the set without any input connected, and see whether it heats up. A moderate heat is permissable, but should not over heat. If it overheats without any load or input connected, the set need service. OK.

NAD 3150 doesn't play any sound


I, too, have the 3150 and have experienced problems with it. With me the INPUT knob is touchy and needs micro turns sometimes to get both channels to come through. Also, it sounds like the pots are dirty as I get a scratchy sound while adjusting the knob. I have been told that these units are great middle of the road audiophile units. Actually, for the price of a used unit you can't do better. I just had an NAD 2400 THX amp delivered today and am using the 3150 as a preamp. My girlfriend is not feeling well and sleeping in the bedroom, though, and I can't listen to it :( The few minutes I heard of Steely Dan's Cousin Dupree made me bout **** myself (until I got the dirty looks). Sorry I wasn't more help! Goooooo NAD!

Need manual for ra 840bx4 & wattage output when remote speakers?


Lets try the simple stuff first. This whole problem could be caused by a dirty switch contact. Pick up some electronics cleaner from a local electronics shop and spray the switch (from the inside of the unit). Work the switch on/off a number of times then respray one more time. That should clean out any dirt that is there. Try the unit again and hopefully the problem is resolved. If not, then the switch itself may need to be replaced. When you get the cleaner, get one that contains a lubricant as well. This will help to prevent the problem from coming back again.

Connect subwoofer etc to nad 3020I stereo amplifier


Hi Info
You can use a 2 x male RCA to RCA female adaptor lead(what you need to ask for)  like this one 4d0dcde.jpg

use it to jumper your pre-out/main in connection on the rear, and connect an RCA lead to the Female socket on the adaptor lead. That will get you going. You can get them most places that sell electronic bits and peices. I am happy to answer any questionsa you may have

My NAD M3 amplifier stops working abruptly.


If NAD doesnt respond , find a decent amp/stereo tech in your area.
I can suggest some depending on where you are.

There's most likely a component failure that regular folks wont be able to fix
