I've listed a few resources for repairing/modding a Technics turntable if you should ever feel so inclined. These turntables are built like tanks. I'm pretty sure you could drop it down a flight of stairs and it would probably still work.
For basic info:
FAQ of Technics 1200Mk2/SL-1210Mk2 Turntables
For the DIYer:
Technics SL-1200Mk2 Service Manual
And last but not least, the MAN of Technics turntable mods:
