There were stereo 45's starting in 1959 but they were very limited in distribution, most of them were made for stereo jukeboxes but some large record stores could get them. Seeburg introduced the first stereo jukebox in 1959 and made a deal with the record companies that they would supply stereo 45 issues of the hit records. Many times the 45 is the only true stereo version of certain hits. RCA even made some living stereo 45's in the late 50's, very short lived. Voice of Music and Arvin both made a stereo 45 only player in 1959, the changer was similar in looks to the common RCA 45 players, but was a completely different design by VM. In the VM model, the arm taps the record edge (like a Magnavox Micromatic) to sense the record on the spindle and shuts off automatically after the last record. The VM 45 player design is the only 45 only player that will shut off after the stack has played. They are extremely rare and I consider myself fortunate to have one in my collection.
