I have an old Meade Dual Axis Drive Corrector for DS-16 AC Drive Model. It is the #43 box that you see in the pictures of the old research series scopes. I don't have a tangent arm or the declination motor. But, any dc powered dec motor will plug into this drive box. I will post a picture later today. Will sell it for $60 plus $10 for s&h. It works fine too.
