Need Final Stage Servo Amplifier for '90-964
I've been trying to solve my A/C-Heat problem(or lack thereof!) in my '90-964-C4 cab.
Currently, I have the final stage servo Amplifier on My bench and to Me,it doesn't look all that healthy. http://i174.photobucket.com/albums/w119/fleetline51/DSC00207.jpg?t=1249044308 http://i174.photobucket.com/albums/w119/fleetline51/DSC00209.jpg?t=1249044351 http://i174.photobucket.com/albums/w119/fleetline51/DSC00215.jpg?t=1249044393 http://i174.photobucket.com/albums/w119/fleetline51/th_DSC00212.jpg From what I hear and read,these units are prone to failing for several reasons. This one looks like it might have spent a few times dealing with water intrusion issues. I was thinking of replacing components but after a close inspection of the method used to assemble the Circuit Board to the Heat Sink, I would consider just replacing the unit with a known good one. (Unless,of course, someone else has a better idea! I'm Hoping that replacing this unit might solve my problems!  Thanks! Tony
