Yamaha R9 "scratching" problem

[FrankE]

i have a great Yamaha R9 receiver/amplifier, ca. 1985. I use it to drive 3 sets of speakers, family room, kitchen, outdoors. I can switch them on as needed from the front panel. I would hate to give up the R9 because of its great sound and 3 speaker control. However, in particular if the volume is turned up a bit, there suddenly appears every now and then a very loud and annoying "scratching" noise. Is this something I can fix or get fixed with reasonable effort and cost? Thanks in advance!

I'd definitely start with some Deoxit on the controls and see if that helps. I've never been inside of an R9 but Yamahas of that era do typically have the cap glue that likes to eat up any components it touches so it may be time for some maintenance.
