Turned out I was getting 163V, becuase TR1 never latched and R1/R2 are removed.
In my good board R1/R2 were dead, I have decided to put new ones - and they are burned immediatly. wtf.
However good board works without R1/R2.
I was able to get 2.7V on Q1 gate and Q1 worked, launching L2 and I was getting 7.1V between pins 5 and 3 or L2 coil. Same as in working board.
But at the time of this experiment I had TR1 removed and after some seconds my Q1 started smoking.
The tester shows it is fine, but looks like it is actually not. Waiting for new Q1 to arrive.
