left channel cuts out on receiver help please
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 |
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 AW "steve s" wrote in message ...

We see lots of relay's with contacts needing cleaning / burnishing.

Steve,
In addition to a bad volume control or a speaker relay that needs attention already mentioned by others, I've also seen these units have bad soldering at the tone and balance control pots. The unit is a decent sounding 2 channel receiver that could give you many years of additional service. If its worth repairing, financially speaking, is up to you.
