Collins R-390A / URR Complete Connector Set for Making Service Cables

this Collins R-390A / URR  Complete Connector Set, is required for Making Service Cables which will allow servicing and testing parts of the receiver out of the cabinet.

 This way you can test the different sections by swapping them out to trouble shoot.

 This hard to find connector set is what the service manual calls for.

 I also have a service manual reproduction in another listing if you need one.

I have taken close up pictures in case you may need them for other uses.

 There are only a few sets available and the pin out information is included.
