This 12v transformer is the updated version of the previous (larger transformer). It will fit newer versions of Laube Corded Clippers. This newer transformer is much smaller, not cumbersome, with easy built-in plug that goes directly into the wall and the other end has loose wires that are for soldering to the circuit board. WE SUGGEST A LAUBE FACTORY TRAINED SERVICE TECHNICIAN FOR THIS INSTALLATION. Otherwise the warranty will be void.
