Thanks for your questions/observations, Jea48!
I have been playing with this table all day and trying to figure out just what might have been causing this as the tolerances from NAS are consistently reported as superb. As I have mentioned, this deck was purchased second-hand and I have been going through, cleaning, setting up (as much as I can given there are really not a lot of good instructions out there)and noticed that the motor pulley groove for 33 1/3 had some gunk build-up in it. After cleaning it out, I observe the speed to be very spot-on. My guess from this maneuver is that the build-up was just enough to increase the diameter of the pulley slightly, causing it to turn the platter just a bit too fast. So, if that ever occurs in others' experience, I would sure have a look at that pulley.
Thanks again. Still no answer to the bearing oil question, though. Would really like to clean out and renew the old oil, which I have a feeling has been in there from day uno!!
