I would think that any amplifier using 400 cycle is a servo control amplifier.  

The AM-1522 and the AM-1734 are two that are used in the ARC-58 and 310F-1 and both have the dimensions, the two pots, three test points and PCB connector that you mention.  The only difference between these two is the power rating of the servo motor.  One of the pots should control amplifier gain and the other controls the hunt dampening.  

I can sent pictures if you like.

A Collins module followed me home from the Shelby hamfest.
It is marked AM-1525A/URC  528-0022-005.
What little I could find on it is that it is an electronic control amp.
It has FSN 5895-00-827-4272 and 5895-00-583-0801and used 110 VAC 400 CPS power.
What equipment is this from?
Does anyone need one?
Size is 4.5"x2.5"x3.25".
It has a single double sides 12 contacts per side PCB connector on the bottom.
The top has 3 tip jacks and access to 2 pots.
It is held in the parent equipment by two red painted screws on 
diagonally opposite corners.

Any data appreciated.
