You didn't mention the make or model of your turntable (1200s?), but in
general, you want to try to calibrate all of the following for the best
sound replication:
1) tracking weight (to the min setting that tracks reliably)
2) anti-skate (at the setting which minimizes channel distortion)
3) tonearm height (parallel to the record surface)
4) vertical azimuth (perpendicular to the record surface)
5) cartridge alignment (tangential to the groove at two points)
Not all turntables will allow you to adjust all of these (usually you get
controls for 1 & 2 and can tune 5 by wiggling the cartridge). For the
most part, you'll need to buy some special tools to do any of the above
the proper way. Be warned that you will end up pissing away at least four
or five hours straining your eyes, so it's probably not worth it unless
you're particularly anal or have some sort of really cool turntable (like
the one Lara Croft has in the Tomb Raider movie).
Besides, if you really cared that much about your records, you'd probably
dispense with the slipmat altogether as a potential source of vibration.
