This is a Panasonic CJ-858U 8 Track Portable Amplifier with a Cassette Tape Pack Pull-Out Adapter, Model CX-888SU.  They are in great condition with no damage or defects.  Both the 8-Track and Tape Player appear to play fine as you can hear them when you listen closely but there is no audio output to the speakers.  I have not had time to do any diagnostic other than initial test with one set of speakers.  Because of this, I am selling as For Parts or Repair.  I will likely do more testing and diagnostic to see about fixing it and will relist at that time.

So, if you want to get a deal on this hard-to-find unit and tinker with it, grab it now!
