Condition is "Used".
Information is to the best of my ability.
Untested but powers i believe it's in working condition because owner took very good care of all of his possessions and I have other items that I have purchased that work well. The Koss ESP-9B set shows very little use headphone cushions still in great condition
All connected wiring is in great shape and complete
No original manual but was able to print one to replace it
Original graph paper included but very fragile to touch
All comes in original box that also is fragile and starting to crumble. Will wrap to protect the integrity of the box and the content inside. Please see pictures for details.
