I switched otu the MAX787 for another one, and the same thing I have looked at the schematic, and I do not see a electrolytical capacitor of some size after the rectifier bridge. Is this just omitted in the diagram or is the diagram an accurate sketch of the breadboard? What frequency does the MAX787 use. An inductor of 50 mH seems to me to be a bit high......
