Bang and Olufsen Beogram 1602

I own (2) B&O 1602 Turntables with an assortment of high end B&O carts to match. The second table was put aside as a replacement in case of total failure. Here is the problem that is making me crazy.

Table one has been working perfectly for the last 30+ years. Yesterday I got it in my head to adjust the tracking pressure. This being done, I proceeded to play a record. The auto play function worked perfectly and proceeded to gently lower the arm onto the lead-in groove. To my horror, the arm jumped the groove and began swinging to the right, scraping the metal faceplate and coming to a stop in its normal position. Hitting the play/stop the arm rose to safety, stopping in its usual position with the usual motor shutdown. The cart at the time is a B&O 4000 and not the 20cl thank goodness.

I tried every combination imaginable of tracking pressure, manual lowering, etc. The only time that the arm would track was at a ridiculously high tracking pressure of 6+ grams.

I considered the first table ruined at my own hand and proceeded to set up the second 1602. Zeroed it out, set it to 1.5gm and and hit the play. THE SAME EXACT ISSUE HAPPENED WITH THE SECOND TABLE. The lack of a manual lift made the whole process nerve-shattering.

For starters, I imagine that the anti-skating function is working too well, pulling the arm across the LP aggressively to the right. What has me going is that the same exact thing is happening with both tables! A coincidence? That's what I need to find out.

Is there any way to manually adjust the anti-skating function? If so, this might solve the problem. If not, can anyone help me figure out what's going on? Ordinarily I would buy a new table--but I am sitting on (4) B&o carts-- (2) MMC-20CL, a MMC-20EN and a MMC 4000. That a thousand dollars worth of carts in need of a vinyl engine. HELP!!
