I am like this circuit, because it is small but very good. I uesd IC - LM317T it is quality products ic variable regulator,so i like make in other power circuit. I made use of a 24Vac 1A transformer,The output of the transformer is rectified by diode 1N4002 or equiv ,and smoothed filter using 2200uF capacitors. The float-voltage measured here for the 24V transformer was 34V-35V,it is unregulated DC voltage. The VR1 is control output dc voltage 0V(1.25V) to 30V(32V) at 1.5A max all range. .It is advised that you use this ic with a suitable heatsink.
