What is it?

[bgadow]

My idea-either a wired remote somebody built for a tv set, or a bench test jig so you could leave the tuner and all controls with the set. I could understand just the tuner-maybe a sub for bench testing-but all those other knobs? All the functions are in this box, or so it seems. The RCA logo is a red herring. This is homebrew...did RCA ever use connectors like that? I thought their tube era stuff was usually hard-wired to the chassis.
