The power cord for the Robyn 8+8 scanner

[MissouriRebel]

The cord used by the Robyn can be found on Ebay . Also, the old Bearcat 4 scanner and several Regency scanners use the same cord. Im in great need of a Off / Volume control for a Robyn 8+8. Does anyone out there have a junker out there that I can buy the part from ? Thanks.
