Yep thats it. If you look real close, you will see loovers at the bottom af the door. That makes it a "real" RCA. RCA only made them for a few years. They came as an option in 1957 in Chrysler cars. A few years later a company named ARC re-produced them. They were very hard on records because of the tone arm pressure. You could drive over RR tracks at 80 MPH and they would not skip. After about a week of playing your favorite tunes....you could hear both sides at the same time. A "real" RCA that works is valued somewhere about $1500. I had several of the ARC's until I found this RCA. Ain't gona give it up. The right person can make them work with the modern radio's. Never had an 8 track. Never liked the fact that you had to play the tape all the way through to hear the same song again. On the RCA all you had to do was hit button before the record was done and it would play the same song again.
OK Doc, did you ever have a "vibrosonic" in your car speaker setup. You know....reverb/echo chamber. They were COOL until you hit the RR track at 80 MPH.
