I'd use an isolation transformer and not put rectifiers on the mains.

IF he had a center tapped transformer, but he's using 240v "mains" as a source.

If he was in America the 240V "mains" WOULD be center tapped - in
Britain or Europe he needs a FW Bridge.

He is in America, but his center tapped (pole) transformer is 120-0-120, where
he would need a 240-0-240 for a 2 diode full wave rectifier.
