The Teac VDRS CMK-4 mechanism is used in the following CD Players :-
WADIA 850 (Version a mech)
My Copland CDP
My Copland 288 started to shred teeth on gear B. I needed these assembly drawings to work out that is was called gear B and what to order from CHS. Emailing absolute sounds proved to be useless as I expected from past experience regarding their support. Anyhow, not too difficult to replace both gear A and B once you know how to. The original gear had turned very yellow and soft. A common fault with some Teac mechanisms.
