With the Acoustic Wave Music system, the power cord does come in two parts, a power pack, and a cord. Do you need both of these parts or just one? The best place to start when looking for replacement parts for your system is always reaching out to your local support team as they will be able to help order any parts they have in stock. As you are in the US you can find your local team HERE.
If they don't have any available, as it is an older system, you may be able to find 2nd hand or 3rd party replacements for the power cord. I wouldn't be able to guarantee how well these would work, however.
I did also have a quick look on the US site to see if I could find the right power cord, interestingly we do still have a listing for THIS travel version that plugs into your car but not one for an outlet for some reason!
I hope this helps!
