Adjustable Power Supply KJS-1509

Hello,
I'm working with a collaborator, so I don't have this unit on hand. I'm hoping to finish a board design, but the polarity of the plug isn't listed. Anyone have one to test? Adafruit staff, could be super helpful to add to the product description.

Thanks,
Josh

Until someone comes along with a definitive answer I'll say that, having used that connector in many places, outer is GND and inner is +V. I'll also add that AdaFruit would do us and themselves all a great service by putting a link to a schematic on the FRONT PAGE of EVERY product. Are we not all geeks that want to know ? No worries about stealing the plans and not buying ---- no individual can duplicate at the great prices offered !
