It's the PCB connector used in the 5245L in most positions (except the rectifier board), single row of 15 fork shaped contacts, single row of 15 open loop shaped tabs on the back for soldering wires & components, two mounting holes built in for chassis mounting, 0.156" (3.96mm) pitch.
See pictures attached, I can't read any part numbers from the topside, can't turn it upside down as I'm working on this at the moment with lots of parts removed to access the decimal point board.
