Piper AutoControl III / Century IIB Service Manual - REQUESTED?

Hello everyone,

I've been having trouble with my AP and have compiled quite a bit of information on how to fix the Autocontrol III and the PET-1 trim motor.

I'm hoping someone has the Century service manual. I'd like to compile a bunch of tips and tricks to fix the typical problems:

-Servo not working
-Wings rocking (oscillations)
-Intermittent operation
-Operation when linked to GPS (not GPSS)

If anyone has the Century service manual, please let me know. Specifically, I'd like to verify the tuning of the four potentiometers behind the Autocontrol III console amp faceplate. I "think" I know what all four do, but I'm less sure about a) the direction to turn for increase/decrease and b) the proper sequence to tune all four / recheck / retune all four.

My AP works very well now. It would have been less than fun to hand fly to Sun'n Fun!

Thanks in advance.
