Panasonic RX-DT77 Portble Stereo CD System. Panasonic RX-DT77 Portble Stereo CD System Radio-Cassette Boombox JUNK. It is a Panasonic CD W radio-cassette player. Does not read CDs. Both W cassettes do not work. The cobra top stays open all the time. I have a remote control. I have not checked the operation of the remote control. I think you can use the radio. Although it is old, I think it is quite beautiful. I would appreciate your favor in a person who understands junk. There is deterioration on the painted surface, but if you repair it and use it, it is a rare product. International Buyers – Please Note.
