Capstan belt recently replaced now play, rewind, fast foward all working properly. Tested groups/tracks 1 thru 8 all record great except group/track 6. Shows group 6 mic input coming in but doesnt record. Possibly easy fix but not looking to put more time fixing rather just sell. All eq and mixer buttons and led meter lights etc all working great but unit not fully tested, selling as is. minor cosmetic wear, switch on back misssing see pics.
