So i recently bought a used 1200 and noticed that I could only dial in 2g of tracking force before the counterweight ran out room on the tonearm. I remember the seller pointing out that the tonearm/weight was uncalibrated, although I assumed that he just meant that the tracking force reading was not dialed in correctly. There is a thread on here that addresses the issue -->http://www.djforums.com/forums/showthread.php?29107-Technics-1210-can-t-put-enough-weight-on-the-tonearm<--. One replier points out a certain "weight" that screws in to the end of the tonearm and to remove this, but there is no picture to refer to. Other than the counterweight, I do not know of any other "weight" that screws in to the tonearm. I could always just superglue pennies to the headshell, but wanted to find a less unorthodox solution.
