I have an LX200 Classic Fork Mount (2001 vintage) with ailing DEC drive electronics. So if you have a replacement set of just the electronics (small electronics board, LED's, and sensors) or a set including electronic and worm gear assembly I am interested. If you do repairs, I could work out an exchange or send mine for repairs.
The problem - when turned on, the DEC motor hums and rattles. When I drive one direction or another, it moves very slow and unsteady. I know it is the DEC assembly, because I borrowed the worm drive with electronics from another mount and everything worked fine.
Advice is also appreciated.
