Thank you very much for these valuable detailed information! :-)
Also following the suggestions of Curious Marc, I focus now on the

Hi Dominique,
Are you using a standard DMM to make your resistance measurements? If not,
you may have more consistent results by using a laboratory DMM that is
rated to measure milliohms.

Hello,
Yes, it is a "Fluke 73" maybe not enough accurate for that kind of
measurements ?

Because I had removed every wires to test transistors on A1 and A2, and
since I have to buy 4 new 0.1ohm resistors and an equivalent of 2N6254,
in the meantime because they are identical I decided to interchange A1
and A2, I was hoping note a +5V collapsed on the other output but no, it
