Phono stage hum


Dipping my toe into Tubes for first time.

Have been using simaudio moon lp5.3 phone stage.

today trying Manley Chinook tube stage.

getting what sounds like ground loop hum with the chinook and my thorens 160 super... tried with a different turntable (cheap teac) and no hum....

any ideas?

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...
