Came across this Panasonic Model #RS-790S this morning for $5.00 at a local Flea Market.It is a full auto reverse machine with either to be used as a Deck or with built in speakers and amp.After a good initial cleaning etal I fired it up and it plays good real good.Won't try recording until a later time when I can really go over it but all initial indications are no problems foreseen yet?Anyone know this R2R or have info on it,much appreciated if anyone has
