[Elecraft] 2.5mm DC power plug ?

[Bill NY9H]

i hate to think how many times I've had to pull out the 
ohmmeter...  to test these frequently wired non-standard... with the 
hot on the shell....

This year already I have blown up an infared headphone base station, 
because of that ... even after I made the measurement , then grabbed 
the wrong cable !!!!!

  it's another reason to have a meter in the drawer next to you....
