Un-Plug the Radio from the AC Power -and- Remove the
Batteries from the Radio. Take an Ohm-Meter and Check
the Continuity of the External Power Adapter Input Jack's
Outer {Rim} Connector to the Plus and then the Negative
connector of the DC Battery compartment. Most of the
time the Outer {Rim} Connector of the External Power
Adapter Input Jack is the Radio's DC Circuit Ground and
is also a direct connection to one side of the DC Battery
Input. With this Continuity-Test you will know whether
the Radio is Negitive Ground or Positive Ground. {The
Radios Circuit Polarity and the Tip-and-Barrel Polarity.}

Next - Take your Radio to RadioShack and buy a 9 VDC
rated at 800-1000 ma AC-to-DC Adapter. Then try out the
various size RadioShack Adapter-Plugs to find the one that
fits your Radio. Now at the RadioShack Store connect the
Adapter-Plug to the AC-to-DC Adapter with the Tip and Barrel
to match-up with the Polarity of your Radio. Plug the AC-to-DC
Adapter in to an AC Outlet and Plug the Adaper-Plug into the
Radio as you finial test to see that you Got-It-Right.

IMHO - The GE World Monitor Radios were the best Solid-State
Radios that GE made prior to the introduction of the GE Superadios
{Super Radios}.
