First as stated before, when I 1st received the unit no hum issue it was after it was sent back twice that it came about. 2nd if I use my other conditioner, a Purist Audio Design all is dead quite. The humming out of the speakers stops if you plug the turntable motor into the wall directly or into the PAD conditioner, same with the phono stage. Plug either or both into the PP+ and the hum comes back. I've tried cheater plugs on each and every componen, no difference. I've tried grounding wires from chassis...no difference. There's also another customer that is having the same issue with his new PP+. He has an original PP unit and no hum so I think it's safe to say it is the PP + unit(s).
Suggestions????????????????????

Sorry, this sounds like purely your issue. Any power devise has own impact to the rest of the system. You do admit that it is hum, I presume 60 of 120 cycles. So, it is poorly the loop issues and the loop in your system. Experiment with lifting the grounds, with ground patches and etc. You have isolated your turntable motor reason the rest is very simple. I think you could blame PP if they disconnect ground at the unit output but I do not think that they did it.  BTW, what is the problem to have turntable motor plugged into the wall? I have my TT motor in the wall for years. Just do not let the motor body to touch anything and you shall be all set.
