[ICOM] cable connector

[Ralph K5JN]

Does anyone have or know where to buy the power output cable connector for the Icom PS30 supply?  
It's also used on the IC2KL cables.  
I'm adding a cable to my PS30 and need one.
It's identified with the letters NK and NC-1.
Google searches have been no help.
I've seen ones that will work but want to stay original.
There was an option cable for the PS30 (OPC-045) no longer available that may have provided the cable connector. 
If anyone has one or the other, please let me know.
