i have the same issue with my classic 1 with my azimuth swifting from one side to the other, and i also figured this by using a small japanese bubble level weighting 0.7 grams made for this purpose. the bubble level is placed on top of the headshell while stylus on a still record.
actually i also addressed this to mike n he has no firm answer to me too how this could happen..
