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

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.

Bob

Two diodes will work if he center-taps two series capacitors to
Neutral, . One end will be +150 VDC, the other end -150 VDC.
