The Astron SL 11A is a 13.8vdc linear power supply. The Dual Core can handle up to a 15vdc input. I know this because I emailed Dspeaker and asked what the max input was.
On the back of the SL 11A there are a pair of binding posts one red(+) and one black(-).
You will need to take wall wort to Radio Shack and match up the plug size (can't remember the size at the moment), buy some 18g wire, crimp connectors, and a digital multimeter, all together about $30.00.
On the plug there will be 2 wire leads.
Strip the wire ends and crimp them to the plug wire leads.
Connect the opposite ends to the binding posts on the SL 11A.
DO NOT plug the cable into the Dual Core yet!
Plug the SL 11A into the wall, turn on the multimeter, take the red probe and put it in the center hole of the plug, take the black probe and touch it to the side of the plug.
If the meter reads 13.8vdc then you are in business.
If the meter reads -13.8vdc or 0 then swap the wires on the binding posts.
You should get a positive reading.
Put the plug into the Dual Core and enjoy a huge improvement in sound quality.
Search for Astron and call their customer service, they will give you a number for the dealer in your area or try Ebay.
