In this video I calibrate a Technics 1210 with a cheap multimeter using the frequency function. First disconnect the pitch board and set vr302 to 2.7K while the pitch lock is on. Then reconnect the pitch board and use the frequency function of the meter to measure TP27. Set Vr301 to 262.08 or as close as possible with your meter and that should be back to factory settings. Looking at the video while editing and I should have set 262.1 instead of 262.0 as this would be closer to the .08 needed.
I used the VICI VC99, but any multimeter that can measure frequency will work. Check out EEVblog for guides to multimeters.
