Hi audioguru, Can I replace D1, D2, D3 & D4 with general purpose rectifiers D25XB60 rated at 600V, 25A? Thanks.

Hi audioguru, Didn't know so many works to be done with low volt transformer. maybe I'll stay on 24v or 30v transformer. Anyway, thanks for your reply.

Thanks audioguru, That is what i want. Can you please guide me which resistor and what value to change.

Hi audioguru, Thanks for your reply. I have a 16v, 5A transformer in hand. Can this transformer run for this project? I really like this psu. Thanks

Hi audioguru, Thanks for your super fast reply. I'm totally new in electronic. I don't think I can build this circuit without the re-designed schematic. If possible, could you please come out with the re-designed schematic or detail in text what and where to change? Thanks

Hi all, I plan to build this project cos the voltage can be reduced to 0v, variable current limitting, over current operation led, etc but my question is that I only need variable voltage ranged from 0v-12v and current from 1mA - 1A. Can I use a wall wart with 15vdc, 1.5A output as the input supply instead of using stepdown transformer? Thanks for reply.
