[AMRadio] Viking Ranger plug

[Rsauvan]

Hi all,
I am looking for the 2 prong plug that goes in the back of the Ranger where it supplies the 110 volts to accuate a relay for antenna switching. 
Im sure they are hard to find if not impossible to find and if so, what can I use? It almost looks like a crystal receptacle but I dont have a crystal 
to try and see if it fits. If I did, I might be able to fabricate a plug from a crystal case. Does anyone know of a source, or have a spare they are williing 
to part with, or any ideas on how to fabricate one so I can get my Dow Key relay working?

Thanks-Bob-W0YBS
