The linear drive unit was originally installed in the mid 80's with an Alpha 3000 auto pilot system. It has been in storage for the last 15 years. The unit comes with the original 80" power/control cords. It is in excellent condition and bench checks as designed. The shaft travels a total of 19.5" from a full closed length including the drive of 27" to a full open length of 46.5". $100 plus shipping cost.
Is your Alpha 3000 drive still available. I have a fully working Alpha 3000 and thought this would be a good spare part to have on hand. Can you explain how you were able to test it? How do I know if it is the correct drive for my unit?
