I wonder if this set is I & Q wideband? It's an RCA VJM 2005 S (1983). I can't remember for sure, and I don't have a Sams book handy to verify, but I think it's a CTC-121. This is the one with a zillion jacks and inputs, including bridgeable video in & out, video level adjustable, and stereo amp (not stereo tuner, and only one speaker). It's basically a Dimensia without the Control ports. The remote is also like the Dimensia; with the removable tinted panel to cover the VCR & audio controls. (it's the original remote)
