Hi all , my SN2 volume control knob is causing crackling in the speakers . I have watched some youtube clips on how to solve this with spraying a small amount of contact cleaner into the pot .( i have Kontact60 spray ) Has anyone done this on SN2 or similair amp ? To get into to the internals do i have to take out the five hex head screws on the underside ( and maybe also the feet ) I presume the the whole internal pushes out from the back to the front ? Anyone had a look inside to do this ? Thanks in advance
Just run the volume knob back and forth a few times every now and then to clean the pot (obviously only do this when the amp is off or at least muted!).

Yup that’s the remedy 
I had tried this before but had no joy , however tried again and was a bit more “ vigorous “ and it seems to have worked 
Cheers for heads up , saves me taking it apart and spraying
