Ty soo much, the anode diode is connected to Drain mosfet, and catode is connected through R2 3k35w to the filter capacitor.
I measured the transformer with a LCR motech 4080A, but a coil measures erratically if someone would be so kind as to tell me if it is an internal jumper or a bad coil.
and this is the information of the rest in case it helps someone.
Sorry for my English.
