Message to all,
You guys are great for the advice. I plan on trying a few thing this weekend when I get a chance. I am interested in the ground loop issue. My dealer has mentioned this to me as well. Are there any tests or fixes for this issue. I was told I should try to plug the power cord in usinf a ground-less adapter.

I'll post again after I have some time to try some of the thing above.

Again, thanks again to all.
