I have a problem with the volume control of my integrated amplifier, everytime i turn the volume theres a crackling noise coming out from the speakers, specialy on the left channel
It's probably dust in the volume control. It gets in between the carbon track and the wiper that rotates on the track, or the resistive / carbon track inside the control is wearing out. As yours is stereo there will be 2 tracks and 2 wipers, one could be worn more than the other.
This should give you an idea. Inside Pot

Hi xaser
Check that someone has not turned on the tape monitor or mute. Both of these may cause the problem. Is there alot of noise with the sound you are getting when you turn it up?

Hi there, get down to your local electronics supplier and buy a tin of spray switch cleaner. Try and spray some into th v/control and do the other controls at ther same time, this should solve the problem

That is a common symptom of not properly grounding of negative side of the output of power amplifier section.Just resolder all component parts joint in power amp.sectiton and double the solder all negative ground.Also clean the pots of all volume controls and selector with a lighter fluid or desame that fluid so whatever sound or crackling noise eliminated and works normal again.. Hope it may help you;;

more than likely you have a bad transisitor on that side and the frequincey is distorted there's not much you can do except take it back if it's new or take it apart and check for the bad part but if you do that you had better know what your doing!! it may be just 12 volts but thru an amp it's a nasty shock
