UNBELIEVABLE: In spite of the video I send, me repeated clarifying the concern not "wobble" but the quality of the machining of the platter edge. This is the response I got from Technics on an "escalated" complaint:
Thank you for contacting Technics Support.
Our engineers got back to us regarding the wobble shown in the video.
In this situation, they advised that you ensure sure the platter has been secured properly with 3 screws, 3 washers and 3 Bellville springs as described in the operating manual.
Thank you in advance.
Sincerely,
Technics Support for United States
