Spooky, the speed on one of my 1210s has just started wandering. I moved the pitch control up and down a few times and it seemed to sort it. I will look at cleaning the sliding pots to start with.
If you're going to open it up it should have a pot for the master pitch adjustment on the PCB. And WD40 contact cleaner has PTFE if you're looking to lubricate as well. Pretty much most of the malfunctions on Technics decks can be resolved by cleaning it seems.
