[Boatanchors] Four Prong Plug For National Speaker Needed

[AB3L1 at aol.com]

A recently purchased speaker needs a plug replacement. Looked  good in  the 
picture! 

It is stamped  H H EBY INC. It has two prongs  larger than  the other two. 
>From a web site I have found it is listed  as a National DCS-10  and is for 
the 
100/101X model  receiver.

Thank you for the help,

Bob   AB3L
