[ARC5] Phone Plugs & Jacks

[WA5CAB at cs.com]

Bob,

The jack is JK-26.  The short plug on the headsets is a PL-54, known as a 
bail-out plug.  The extension cord that they plug into is CD-307 or CD-307-A.  
Plug on the other end of CD-307 is of course PL-55 or later varients.  The cords 
were made in various lengths from 36" to 120", with the 65" being the most 
common.  The later number is CX-4548/U.  There's also a Navy Type Number for 
this cord, Cxx-49534 or 49534-A.  I don't think you'll likely have any luck with 
Switchcraft or anyone else these days.  I have a small stock of NOS JK-26's 
mostly removed from CD-307-A's when I used the balance of the cord to restore 
other equipment (LS-7's, RM-53's, etc.).  I also have CD-307's.  So does Fair of 
course.
