[Elecraft] 2.5mm DC power plug ?

Clint:
The while line might designate the positive lead, but why guess?  The 
best way to check is with an ohmmeter.  The lead that measures 0 ohms 
with the outer barrel would be the negative lead.  You can check the 
inner connector while you are at it, to make sure there are no opens or 
shorts anywhere.
