Sony HFP200 hifi stereo processor unit made for use with Sony Betamax VCRs that were model # "HFR"-- (the SL-HFR60 in pic is listed in a separate auction)--

These were for adding hifi stereo sound to regular mono beta VCRs -

They also can be used (w/VCR) as audio only tape decks that were capable of astonishing (near cd quality) recordings-!

This one has very low hours, and is the deluxe 200 version and it was tested and sounds/works beautifully- 

Cosmetics are nice also- maybe a couple small scratches and the headphone knob is missing- 

Any questions, just ask and Thanks for looking-!
