Default help needed to use my old transformers for F5

I have dug out from my old collection two 200VA, 22V-0-22V transformers (not twin winding, but centre-tapped). I would like to use them for my F5 project. How do I use these? Have one each for each channel?

How do I use them for a Pass PS design, which requires 2 separate windings? I can connect a bridge rectifier to the outer 22V taps and use the centre tap for '0V', but does it give me full wave rectification?

I am quite rusty on my basics right now...

Cheers.

Here's a Pass DIY PS that uses CT transformer.

(But 22-0-22 gives about 31VDC rails before losses....)
