+/- dc power supply

Hi there

I am wanting to build a new psu for 2 class d amps that I have to get rid of the bricks that I am currently using.

I have seen on eBay and other sites a number of circuits for this purpose that would allow me to mask use of some toroidal transformers I have from older projects.

My questions are as follows...

Can I plug one amp into the +dc and the other into the - dc?

How can I get only + dc out of one of these boards?

Is there a better option?

Look forward to hearing from you.
