I recently received a Dentron DTR-3KA 2KW antenna tuner but it does not have a power cord. I can make a cord but need the female plug that goes on the end. This plug format looks familiar to me but I don't know the plug designation or part number. Need that so I can source it. Can anyone let me know the manufacturer part number or common part designator for this plug? Or, even better, provide a link of where to buy one? 73 MJ KG6SSC
