I am very confused about my choice of power transformer. I would like to get around 330V. 250V RMS will get me this with a bridge rectifier configuration and a regulator (using the Morgan Jones set up).
Here is where my confusion starts. If I look at the Hammond web site, all there transformers are center taped. I.E. 250-0-250. That’s fine, I know I just have to use the two diode configuration. However, when I set this up in my modeling software
(Linear Technology switchercad III

)
I end up with 0.5V of ripple at the output that I did not have with the bridge rectifier.
My inclination is to order a 125-0-125 transformer and leave the center tap un-connected. Presumably, this will get me 250V RMS and a lower ripple
Is my thinking correct?
