I've done more tests. I soldered 200nF between the comp and gnd plus plus the choke common mode choke and 4 capacitors 1000uF. The feedback loop was calculated as if the output capacity was 7000uF and the ESR was 3.57mohm.
Now the whole thing works much better. The transformer at small loads is slightly playing but not terribly loud. Certainly much lower than before.
He also adds graphs of output voltage, evaluate how it looks.
LOAD = 2.5A
LOAD = 5A
LOAD = 7.5A
LOAD = 10A
LOAD = 15A
LOAD = 20A
