[Collins] module identification

[Glenn Little]

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.
