I too have a Thorens TD 160 (Mk I) that is now out of service but at one time was suffering from a hum problem. Somewhere I found instructions for a cure which involved altering the grounding scheme on the rudimentary power strip inside the plinth. It was a snap to perform and worked. So yes the problem probably is turntable specific.
It seems I found the cure on either Vinyl Engine or more probably, on a vintage Thorens website. I will see if I can dig up the info but it did get rid of the hum...
