I was finally able to get three total Audio Control Panels. Two identical ones, and one slightly different. My intent is to put the two identical ones in the Pedestal, and the third one into the overhead. I’m hoping I can interface them. I purchased all three of these on ebay from AircraftStock. He’s got great stuff at great prices. If anyone has tried to source these pots… it’s a much better deal to just buy the whole ACP.
