Being the new owner of a used LX200 10" , I am puzzled by the following problem. When I use the keypad to adjust the scope in RA, the drive motor pulsates which causes a jittery image. I removed the bottom of the base on a suggestion from Meade. Hoping to find a bur or stiff grease on the drive gear, I found that the gear shaft and motor seem to be moving constantly back and forth only a fraction of a degree. This movement is reflected on the ammeter as a pulse. This pulsing movement of the RA motor causes the scope to jitter when using all of the RA speeds except for the high speed slewing. Does anyone know what could be causing this erratic behavior??????? please help
