Bought one off ebay for $11 shipped. It's A brand new older Channel Master Multi Switch. 2X4 Grey and rather large. I couldn't ever get it to work. I took it apart and lo and behold, except for a few diodes and a some Surface mount Fuses. The whole board was blank. All the stuff that should be soldred in there like the ic;s and transitor. There were just empty holes.
