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.

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 :)

I have one from a 93. E-mail me if interested.
Thanks, Bob
