If the volume crackles when turned then it probably will be the volume
potentiometer. cleaning it with a contact cleaner inc lubricant (not just a
cleaner/degreaser)
will help. If the carbon track is too worn then the only option is to
replace it.

Other cutting out problems may be more due to dry joints around the amp
pcb. since its a fair age there may be fractures, particularly around the
transistors

Hello..I have an old denon dra 425r receiver. The left channel cuts
out...for awhile playing with the vulome knob helped. I also cleaned a few
times..which also helped for awhile...but now it seems to do it more
often...Is this problem worth repairing?....I took it apart and the volume
knob looks fairly easy to replace...if that is what is where the problem
is.
I have had this happen to several stereos so it must be a common problem
once they get to be older.....any help would be greatly
appreciated..advice
etc...thanks

steve
