I also owned the RCA CED machine. Mine was about the last model they produced. It had all the bells and whistles. The CED was RCA's last electronc innovation and pretty much nailed the coffin shut as RCA went deeper in the red. RCA spent millions developing, promoting and advertising this doomed stylus in the groove technology and even opened company owned stores that only sold CED discs and players. GE finally jumped in and bought the ailing company. CED discs were produced for several years after the last players were manufactured. Check out this site for the complete CED story:
