- Even at 40 years old, some old Stereo receivers can still deliver quality stereo sound with a minimal amount of service. Such is the case with this old Yamaha. It served it's owner well for decades and then developed a few annoying defects that parked it. In this video I bring it back to it's former glory.

Good job.
My grandmother used to have a Yamaha exactly like this one. It was in a basement with a bunch of furniture and random crap.
Wish I had gone and grabbed it, so I could follow this repair guide of yours.. But it was all taken out to the dump unfortunately
I'm in Europe
The thing that gets them parked is the non-conductive film on the Volume-balance control. One or both speakers just seem to die. So easy to fix.
Why not use De-oxit instead of WD40? It’s made specifically for cleaning/protecting contact surfaces.
More a matter of past association and availability. It indeed might work and even work better, but this is the first I’ve heard of it.
Short answer: Deoxit is a very good product designed specifically for this application. It would work superbly in this application.
I see a few draw backs making this a pure judgement vs total cost decision:
WD-40 has the flexible straw container. This makes treatment mush easier to avoid any unnecessary disassembly. The plastic straws or paint type sprays are not as effective.
Deoxit is three times the cost per unit volume.
Around here, only the Guitar Center stocks it. Everywhere else it is available to order. Wal-Mart will be glad to order it for you.
If you just want contact cleaner, everybody that sells electrical carries that in several brands.
