Lost a power cord to FM transmiter, How do i replace?

[XKxWill]

Went to radio shack to get a universal one but they said they only do Ac to DC

One I need:
input 120V AC 60hz
output 14V AC 300mA

There are 14VAC wall transformers on E-Bay. Many of them are screw terminal outputs. You would just have to find an appropriate cord.
