Has anyone accomplished this? There is a connected speaker on the mainboard with + and - terminals, can you run RCA audio right from this or do you need to add something? Also, the RF cable that goes to the switchbox has a center lead and ground which I can also find, but that is the signal LEAVING the RF compartment. Anyway, a schematic would help - so if anyone has a 300 schematic it would be appreciated. If you aren't sure about the video and audio -- once I have a schematic I can deliver it to Dr.Jones and then I'll tell you what he says!!! (Then I will complete the mod of course). Thanks & Peace, GAMMA
