Thanks. Now I can see what we're working with.
1/ For using the Sony speakers you'll need to buy some speaker cable/wire (lamp cord would work fine, too so even your local hardware store can help out). Bare the ends at each end of an appropriate length (wire strippers are a nice thing to have but you could carefully use a knife), one end to the labeled "speakers" output terminals for speaker set "A" (the spring clips) on the back of the Sherwood, the other end to the speaker's terminals. Keep polarity (+/-) same with each connection. You can download the manual for this unit at hifiengine.com btw, and it also explains how to connect your speakers.
2/ For attaching the bluetooth adapter (hopefully it is a transmitter) to the receiver I would still like to see the specific unit so I can see what it's about, but you should be able to get appropriate rca cables (intact) and go from either the tape or vcr rca outputs to the bluetooth device assuming it has rca inputs.
