Query: defective manufacture

This was purchased for me as a gift. It soon began to exhibit repeats through a disk, any disk -- usually from 14 track onward. I only listen to books on tape on the player so the problem is particularly annoying. Once a track is completed, instead of advancing, it begins that track again, and again, etc. This is not due to motion or bumping. To proceed, one must manually advance. A replacement was sent by Amazon. Unfortunately the new unit exhibits exactly the same problem.
