Now I figured, that there was an overlapping in switchtime. SPSUs use to have abt 48% dutycycle on each half. I had over 50% on-time on the FETs. By cutting off the schottkys, I managed to get that thing running. Not yet measured ultimate power, but at 200W in I get somewhat over 160W out. What did that teach me? Never trust nobody, not even a schematic, hi. Thanks to those who tried to help and 73 to all of you, Peter, dj9dw.
