The potential of the ground rail (0V) is greater than the potential of the negative rail (-15V), so the caps are correct, with the positive side going to the higher potential (0V). > Hi 2 All > > Look at the attached files, it's a schemes from 2 sites , look at the > capacitors mounted on the negative rail. > which one is correct or I miss something here? in which order should be the > capacitors on the negative rail? > -- http://www.piclist.com hint: The PICList is archived three different ways.
