nad c352 volume control static

Ive been getting some static with my nad c352 amplifier when i adjust the volume knob, does anyone think this could cause speaker damage ? only had the amp for a year or so and otherwise it works perfectly, bought it online so returning it would be a hasstle.

 

Do you mean pops and clicks ...or a belt of static ?

If pops and clicks this could just be dirty tracks .....switch unit off rapidly rotate the vol pot back and forward a dozen times and see if the pops and clicks have moved or disapeared. The static shock is you not the unit.....your grounding your self to it causing a spark ..normally cause by synthetic carpets and nylon shirts.

 

You could ask a TV repair shop to check it. Amps should be straightforward to them, and fixing something that still works is way easier than fixing something after it fails. It could be a faulty pot, or soldering, or a preamp DC problem.

 

thanks for the advice zanash - did what you advised, turned it off and rotated the volume control a few times and the static has gone

 

Fantastic job ................................next unplug unit .....remove case and spray some switch cleaner in to pot.....rotate back and forth as before.....leave for ten minutes reassemble ....listen to a clean pot!
