Hi Martin,
The problem of the tonearm being dragged across the record has been located, if not permanently fixed.
The issue is at the senor which “thought” the tonearm was too far to the right, hence the leftward drift. Once adjusted the up/down function is back and the 4002 is again playing records.
Unfortunately, after a single play the tonearm appears to be pushing too hard (or too fast) to the left and first bends the stylus to the right until the stylus is dragged over several grooves. This tonearm adjustment certainly gets out of adjustment FAST!
At least we know it is not a serious problem, but I don’t know that I want to try another adjustment today.
Thanks for all your help!
Jeff
