Denon DP-1200 turntable

I have not had this connected to my system in years...partly due to space restrictions and partly due to the platter rotates at a very high speed no matter how I try to control it. Years ago somebody told me it probably needs a new servo? In any case, to what repair price point should I go with this before considering a totally new turntable? There are not other defects that I am aware of and it's still in very good cosmetic condition. This was a better than average tt in it's time but I really have not kept up on these over the years.
