Newbie needing some help here. I built the Mnats little PSU (http://mnats.net/psu.html) to use as a power supply for a pair of W492's. As soon as I plugged it in C3 and C4 smoked. I checked and triple checked the orientation of the diodes and the large caps and all is good. Of course I have a healthy fear of power supplies and up unitl this point all the power supplies I built (1176, API 312 and Green Pre) worked perfectly from the first start up. Solder joints are also all clean. What could have casued this? Any help would be greatly appreciated.
