Not sure how this comment is relevant to anything going on here other than you taking a shot at someone.
But there are far more electronic parts present in the Technics, which is likely where the issue lies with this specific table.
Right, perhaps something was jostled during shipping. Or, and not to accuse, but what if they original owner attempted some goofy modification like adding a KAB strobe disabling switch - a mod designed for the original SL-12X0's ? I'd look carefully at screws to see if there is any evidence that they've been backed out. If so, then I'd ask for $$ back outright.
