This is how I wired it

I wired it as full wave with the centre tap to zero volts and CLCLC filter. The boringly obvious. After all the filtering it went down from 178v to 155v. I didn't use the full 250v winding, ignoring the centre tap.

I think I need the whole of the current rating, so what I've done in the past when I'm short of volts is to add another smaller transformer. I would in this instance take a small 24+24v transformer and add 24v on the end of each side of the HT windings. That should take me up to something like 185v final voltage if I needed a bit more. I've only previously done this with a bridge rectifier - I imagine it works with a centre tap as long as you get the phase right. Can anyone confirm?
