I have a mint condition Pioneer RT – 707. I know one of the specs for these decks used to be wow and flutter. Wow does it have wow - almost slows to a halt at times and lots of chipmunks at either speed. FF and Rew seem to be OK although rewind tends to spill a little tape. Previous owner says he hasn’t used it in a while and says “the wheels may need lubricating” but forgets how to do it. No manual. Can anyone help?

Thanks,
John
