General purpose Radio Shack plug-in AC/DC adapter. Output 12 VDC 1A.
Output is via a 6-foot cord which originally had interchangeable tips, but
now has only one (5.5mm concentric barrel plug). The tip is reversible so
can be either center positive or center negative.
Pick up at our house in Derwood, between Rockville and Gaithersburg (near
Briardale Road). Please check my other offers in this group. I have more
stuff just waiting for the right person to need it.
