[QUOTE="Snapper_Slapper, post: 8343229, member: 645213"] You can just solder across the pico(the little one with the P). You can also just solder a ground to the RCA ground trace. In the pic you posted, where the RCA's go through the board are the pos+ part of the plug. Turn the board over and you'll see where those lugs come through the back side. Right beside those will be either 2 or 4 more lugs just like the pos+ lugs soldered on a common trace for the neg- side of the RCA plug. All you have to do is find a close ground point and solder just about any small wire from the ground point to a ground lug. It's easier than trying to carefully bridge that tiny pico. I just fixed mine that way. I had the exact same problem you have and now my head has 0 noise issues. [/QUOTE]
