This player was acquired by me as part of a collection that belonged to Gunter John, the Head of Mastering at RCA's Rockville Road factory. It was open and appeared to be new in the box. After a full service it roared to life. It looks and operates fantastic. It has everything that would have came with it new from the factory. It is a SKT400, the last player that RCA produced. This specific player was built Monday January 9th 1984. It was most likely purchased by Gunter from the RCA Family Store, where employees could purchase RCA items at a discounted employee price.
