Well, I reversed the L/R to the cartridge and the silence remained in the same, right speaker. I then reversed the tonearm wire that connects to the preamp (while the wire to the cart was still reversed), and the silence switched from the right to the left speaker. Now I am more confused. In the process I found that the hum ceases when I remove the ground from the preamp. Is this a ground loop? The strange thing is that the hum is only present in the silented/attneuated channel. Do any of you brilliant people have any insight as to the cause of my problem? Thank you
