[Elecraft] 2.5mm DC power plug ?

[David F. Reed]

Clint,

you can either assume you are right (which I believe you are), or you 
can very easily test it.

I recommend testing, in case you have an open or short at the plug; a 
simple ohm meter test, or continuity tester (honker?) could save some 
trouble down the road.
If an ohm meter is unavailable, just a simple series circuit would 
suffice to determine the properties of interest.
