*aching* to point out that you have already decided to try to have more hardware made... But I guess it wouldn't be worth the effort to put RCA-outs on the tuner (would probably requre another chip?

About designing this board... could the MPX signal simply be Y'ed off the connection between the tuner and the empeg? And then processed separately while the other "half" goes into the player as usual? Or would this degrade radio quality? or volume?
