NuTone in wall sterio system

I have a NuTone in wall stereo system that I am not sure is worth fixing up, selling or recycling. Not sure how old it is. I have 2 in wall speakers with the in wall boxes, one box has been modified to allow wires in wall to pass through. There is a reel to reel and turntable, with the amp/am/fm/intercom and one intercom box. I do no know when it was last used and if it works. I will need to try to power it up.
