Finally I changed PA transistors Q7 & Q8, because I shorten Q7 between 
Base and Collector by accident with my probe... no big deal...

Now, tuning at 2W I have again these readings:

Both Q7 & Q8

B : 0.6 VDC
C : 0.0 VDC !!! (should be around 13.3 VDC
E : 0.0 VDC

There is also the readings I have with driver Q5 when tuning at 2W

Q5

E : 0.6 VDC
B : 1.2 VDC
C : 13.4 VDC (should be 12.4, but... )

Any idea ???
