Oh this is one of the Carousal players you mean 5 disc not 50. Yamaha did have a 50 CD changer that used the Sony mechanism, they were not around very long. These Carousal players are very good, and in fact killed off the other changers. I have a Samsung carousal player in storage I have not used in years. They are quiet a bit slow by modern standards and unlike the drawer changers there is no chance it will damage your CD's. I don't use mine anymore as I can access 100's of 1000's of music tracks in a fraction of a second with just a mouse click. Enjoy it Yamaha makes good stuff.
