or get it from coldamp.com

what's the current you need for the rail voltage?

Boleh-land?

Thanks for link but the cold amp module is out of my reach. The only stumbling block to build my own smps is always the output transformer. No confindent to wind it myself. Do you know of any local winder which can wind smps trafo according to spec?

yeah....boleh-land itself

no idea where to find local supplier for winding
..... i'm in the midst of building the PS for my car as well....
in the 1st stage now, on the SG3525 part

will try to wind myself later stage .... dont know will be successful or not

also plan to bring in the coldamp as well in near future for a try

Or just take PS out of an older amp.
