Well I spoke with Gary, and ruled out a bad amp. The fact that I'm hearing it in the headphone jack and output jacks rules out bad amp. Since the amp is bypassed when plugging in headphone as well as the output jacks. I went and purchased an inexpensive adapter to bypass grounding (hoping it was the ground wiring in my condo, and that didn't fix it either). I'm picking up something from somewhere that's for sure. When talking to Gary over the phone I mentioned that placing my hand on the side of the left speaker caused the noise to go away, so I must have blocked whatever the mystery signal or wave is in my home. I guess I'm going to have to contact Steve next week and see about having extra shielding installed inside the keyboard. Unless someone else has an idea that was not mentioned.
