Dead NAD M15


Hi,
There are fuse inside Nad M15. If you open the top cove then you can see there are 9 fuses lined up i the circuit board on the right side of the transformer. Check these fuses. Also check is there is any fuse behind the Power one of switch. If it is faulty the replace the same.


Before connecting the power after replacing the fuse. check the working voltage marking at the back side. Is it 120v or 220v. If its 120V then be sure that you are using 120V AC line.


If any fuse blows of when you connect the power then you have to consult any nearest service station.


The Voltage rating and Amps rating of the fuse can find marked up on the two metal strips at the two ends. My be laser mark or punching.


Check the link bellow to see the fuses
Check the 12th picture on the link.

I have a visonik 800watt amp and i got it from a friend for free and i hooked it up right and as soon as i turned it on the 2 fuses blew then i replaced them and tryed it again and it stoped again so i...


Its the amp, do not put any more fuses in it
you need to get it checked out by a technician.

Its probably a power supply fault or blown output devices.

Hope this helps
Thanks for using FixYa

Left channel is not worthing


Hi, it could be the output relay, or fuses, have you checked the output fuses or any fuse that has blown, Check for anything that shows signs of overheating.May be the output transistors could be blown. If you are not qualified then i would suggest you get an engineer to look at it otherwise you may end up in hospital or even worse DEAD.
We don't want that to happen, do we.

If yo need more help , please ask.

Need a fuse for Sansui stereo amp I purchased at a yard sale. Radio shack cares the fuse but doesn't know exactly which one.


Difficult question. Which Sansui amp? You could start small, say 2A, increase by 1's till it doesn't blow or if that is too expensive, 2, 5, 8, 10, 12, 15, get the idea? Just don't start big and expect it to work properly, the fuse that is, it is supposed to blow, not "let the magic smoke out".

My sansui qs 1 immediatly stopped working and alll it does is hum can not find any burnt components


Good day sir, there are several reason why the amplifier hums, but lets go to the common ones,
  1. The main power amplifier is defective. Does the volume control affect the loudness of the hum? If no, possibly replace your main amplifier IC. if its transistorized, check the two push pull amp. for shorts.
  2. If Yes, check for shorted audio cables. just maker sure you are using a good audio cable. or
  3. The pre-amp IC is defective, usually op-amps. try replacing them one at a time. these requires unsoldering and soldering.
  4. If you want to find the faulty part, you may need to trace a signal, you may need the folowing, an audio source, sine wave generator, an oscilloscope, or a portable amplifier. This method requires you to be techie. Feed the input with the audio source (disconnect first the speakers so that the hum will not bother you.) check the output of each stage, from preamp to power amp. identifying where the heck the signal dissapper. and where the start humming appears.
The third one requires a lot of work, just bring it to a service center.
Hope this helps, feel free to ask again, let me know your progress. Thanks

No output from my receiver


Some of the older radios are worth money, seeing how they are antiques, so I would research yours, make sure how much it's worth, check tube prices, try to find one on ebay or some other place, and repair it, because chances are it could be worth money.

hope this helps you out

That was a dumass response and not helpful. I have the same amp and same problem. If you don't have an answer, own up to it.
