Electrical problems?

I have this plops from my speakers during LP playback. They definately do not happen with CDs.
I believe that loud passages trigger these.
Also when I use the cueing in my ET2 tonearm sometimes there are these horrible noises, similar I believe to the plops during playback but in a raft mode as I move the cueing lever.
I have grounded the Teres motor pod to the middle socket in an electrical outlet, along with a wire to the grounding screw in the preamp (this ATC-1 Air Tight has a two prong connector without ground), even a wire to the metal axis of the vta adjusting lever in my ET2 tonearm. I have tried connecting and removing these for different combinations but this is not gone.
I also have a miniature tester for gounding from RadioShack to make sure that the grounds are correct in the outlets, and to cap it up I am now using a Monster 2000 power strip JUST to try to spot a solution to this problem and I believe that with the grounding improvement from using the tester and this power strip I have been able to reduce it but I am not sure and definatly not altogether.
Any advice will be greatly appreciated.

Alanpiga,

I don't know if it's relevant to your noise, but how did you ground the Teres motor pod at the motor end? Grounding the case does not ground the motor.

There was a discussion of this recently on the Teres discussion forum. Chris Brady chimed in to offer an effective method. I'm afraid I don't remember the details, so I'd urge you to join that forum if you haven't already. The discussion would be in the archives, no more than two weeks ago.
