out into the room, probably better off keeping it in the wall! I have found that caps subjected to AC are huge noise polluters. In another project I built a shield for the inside of the EQ unit that came with my Infinity RSIIb speakers, around the rectifier section of the board, using TI-Shield (picture #1). Two 1000uF caps in that circuit were spewing noise out into the rest of the circuit, and this did a great job of reducing that. The reduction in background noise from the unit was substantial, as shown in the pictures #2 (before) and #3 (after) below.
