3012/ii Hum or tube?

Vinyl Asylum

Welcome Licorice Pizza (LP) lovers! Setup guides and Vinyl FAQ.

Trying to trace a hum in a Thorens TD124/3012/ii. Is it possible that a hum has started because of a phono preamp tube or is it always a grounding issue with the arm? One thing: if I disconnect the ground wire from the arm to the phone preamp, the hum turns into a buzz.
