thanks everyone for the responses, i would love to just rebuild these i have done it before and really think that it is a great device. the issue is the company(s) don't want to cover or limit what they will cover in repair and rebuilding these. and the customer does not want to pay to have it repaired/replaced/repaired. so caught between a customer that wants the elevator running and a supervisor that wants the callback cutdown.!? i will check into Electrodyn and see what they have going on.
