You cannot power this unit from a transformer. Transformers supply Alternating Current (AC), but the unit will require Direct Current (DC). In addition to the transformer you will require a rectifier to convert AC to DC and a smoothing capacitor to remove hum from the rectified DC. A 12V (13.8V) supply as used for powering CB radios would be a suitable supply for the unit.
