hello, everybody

I' m new on this forum, "sorry for my bad english, i'm french".

so, i would like to build a simple SMPS with tl494 with +/-30V and about 15 A.

I have seen the post of Risto80

and i would like to modify is pcb"if risto is ok"

with over condensators about four 10000µF to output of the power supply and have 15A or more.

someone have an idea to proceed?
