It works now, at least for a full week
I have to thank you Russ for the help and patiente, the resistors test was essential to see it was a mosfet failure I order DN2540 ones and installed them. They are working.
I have now 260/270/280VDC (it depends wich valve i use) 12AT7 plate voltage and 2.2VDC cathode... the valve runs at 10mA. A little high but i don't have a more suitable resistors.
