Using a Philips #1 Screwdriver unscrew the two 14.8 mm screws connecting the transformer to the mounting bracket.

Hold the nuts in place while unscrewing the bolts using a 9/32" Crescent Wrench (or pliers if you do not have a 9/32" Crescent Wrench).

Although the transformer is released from the mounting bracket, it cannot be fully removed yet because there are still cables holding it to the circuit board that must be cut.
