Dear Phil, I believe that you know how to build ps. If i want to build the best possible ps using Superteddyreg than i am trying to use best possible components around it and a oversized high quality transformator with low impedance is IMHO a good choice, or is there something wrong about it ? The main cap after rectifier is 6800uF. Most people will also say that it is too much, 2000 will be enough. For me the price difference using better oversized components is maybe 20. So what ? -- praganj ------------------------------------------------------------------------ praganj's Profile: http://forums.slimdevices.com/member.php?userid=41091 View this thread: http://forums.slimdevices.com/showthread.php?t=82648
