More and more I think it is important to document the condition of a piece of equipment prior to shipping. Not just photos but also a video with evidence of the date which shows that the equipment is working. And then pay for packing by FedEx etc so you aren't accused of improper packing. I am not sure how it could be more likely that the recipient damaged the coils...
Just sold my Dynavector XV-1s
Sold my XV-1s to a Audiogon member with no feedback. He emailed me that he had only one channel working. It worked perfectly when I removed it and put it back in the original packing to send. I told him to reverse the cables from his T.T. to phono pre and see if the other channel worked. If the same channel still worked he had a problem with his T.T. Any other ideas...
