I have a Luxman R-113 that I've own since new (mid 80's). My right channel has started to distort and sound like it is not getting full power. Sometimes I can play with the volume and it will come back but only for a very short time. After searching about similar problems on this site, I did the DeOxit treatment on the volume, balance, treble, and base but still have the problem. I tried switching my speakers to option B but still have the problem. What else can I try or do to find the cause of my problem? There is no local repair shop in my areas that I could bring my receiver for repair. Thanks!
I think a bad relay is a common cause of problems on Luxman units of this line. It also fits in with the symptom you're describing.
Yes, there is a relay RL1 in series with the speaker selector switches. Maybe it can be cleaned, but replacement would be best.

Thanks for the info. I will locate where this relay is located and see what I can do. I assume this relay is most likely soldered into a circuit board or so other component in the receiver? Where would I be able to purchase a new relay?
It's a little white, black or transparent plastic box. Usually about 1,5 x 3 cm in size. Sometimes the plastic cover can be removed, and if so, you can try cleaning it by rubbing rough paper (NOT sand paper) soaked with some solvent (window cleaner or whatever, dolesn't matter) along the contact surfaces within. This will usually fix a bad relay.
Getting a replacement is probably easy, but there are thousands of types available. You'll need to find the specs of the original part. It's not critical. Most likely any double pole single throw (DPST) normally open (NO), 12 or 24V and 8A current rating will do. But make sure the pinout is correct.

I found one plastic black box but the cover is not transparent and can't be removed. Would this relay also do the "click" delay after powering the unit up?

Yes, that's correct.
If you provide dimensions and whatever it says on the relay top, I can probably find a suitable replacement for you.

I did not see any writing in the relay but I will get the dimensions and post back. Thanks!
