Tested everything works great. Unit is in great condition and was well taken care of. Includes remote control, which is also in pristine condition! See pictures. Does not come with the original box, but I will make sure to package the unit with great care This Nakamichi cassette player and recorder is a top-of-the-line model with a variety of features and functions. It comes with a wireless infra-red remote connectivity system, allowing you to control the deck from across the room. The gear drive for the spool motor and the direct drive capstan motor ensure smooth and precise playback, while the pressure pad lifter helps preserve the quality of your tapes. Some other features of this cassette deck include auto tape sensing, real-time elapsed/remaining display, and auto calibrate bias/level/azimuth for optimal recording quality. The 60dB wide fluorescent display provides clear and easy to read information, and the auto azimuth adjust play head ensures accurate playback. This unit is in excellent condition and ready for use.

Very nice condition Was just in use but owner had to move into a nursing home No remote Comes with cords as shown No reserve auction
