Default How much power can I have with (+)

Big n Fat halogen trafos - they're toroidal and fairly cheap, but have only one winding and are 11,8v, maybe I can just unwind it and wind double winding(I dont have enough thick magnet wire...)
So heres the question - how much power I can have with tda7294 or lm3876(bridged or unbridged) assuming that I feed those with two halogen trafos, one for (+)rail bridge rectified, second for (-) rail bridge rectified too(around 24v unrectified, VA's nearly unlimited up to 750...) ?

It's around +- 15V after rectifier. And with 4 Ohm load you will get a maximum of 25W (undridged). But these halogen transformators aren't very good for audio.
