Hi, all but the bottom row of GM-300's and the one for the IC-7300 (NovexComm) came from Alberta Radio Supply
Edit: I was remiss in not mentioning Alberta Radio Supply apparently! Yikes...those panels obviously play a major part in this setup. The 4U IC-R8600 panel was custom made for me by them. It'll probably morph into a 3U custom made one...via the magic of my wallet. Ack. Oh well it's only money. Reason? If I go back to the rack mounted 1U mixer such as the oft-mentioned 1602, it'll sit right in above a 3U mounted 8600.
