I just recieved my coupling caps and Trans. so tommorrow I start lay-out. Were you able to use Damir's photos for your CCS boards? When you say boards; do you mean PC boards and if so where did you get them etched? You never stated if you got the red LED's or where you got them. I'm trying to form a mental pic of the set-up over the I-Beams. What exactly do you have tied to the beam? If you ended up using the wood side panels how are mounting your RCA inputs?
