hissing noise when turning volume knob?


hi audiogon fellows, recently i have detected noise(like radio tuning) from my right speaker, only when i turn the volume knob. Firstly I'm pretty stupid with machinary stuff, i'm guessing it might be one of fuses is about to get blown out.
I have no idea what causes the problem, strange though the noise stopped for awhile, and then back this week, and there is no problem at all during listening.
I just hope it doesn't die on me anytime soon.
BTW my amp is Plinius 8200mk2 intergrated.
Thanks in advance!!

In some cases, if you rapidly move the control up and down many many times, the problem will minimize at least temporarily. This action "cleans" the internals of the Pot a bit.

Obviously be careful, either turn the system off when doing it, or, make sure the volume does not exceed reasonable levels.

If the problem minimizes, the Pot is dirty..in most cases the hash will return soon.
