I am not the original owner of this deck; so I don't have a reference. Is this as good as it gets or has age affected the circuits. I work on vintage electronics; not an expert but I have done a lot of repairs. Other than the speed issue I like the table. It is in great condition. I use it off and on. I must confess to liking the ease of use with my Pioneer PL-600.
So I'm not sure what you mean by you can't get the strobe to stay still?
When you adjust with the pitch control do you reach the end of the pot turning either clockwise or counter-clockwise and the strobe still doesn't stand still?
If that is the case, set both the 45 ans 33 pitch controls to their mechanical center. Then underneath the platter there are two additional pots for 33 and 45 that you can use to center the pitch controls. If I remember you can access them with the platter mat off through the holes in the turntable platter.
