It means that they did not respect the pin connections and we have to identify them correctly

it is built for pcb mounting so the side with the pins should be the bottom

yes green mark on TA pin 2... but their documentation doesn't say that!
Why ? why do they have to complicate simple things!!!
One side the entrance, the other the exit! is that too much to ask of them???
Pfff... Electronics are already complicated enough (for me) without adding illogical things and especially manufacturer diagrams which do not reflect reality...
I'm tired

enfin! c'est ça.
yes that's it. we see that you are used to it micolas!I would never have thought of measuring on either side of the transformer... for me the left side was necessarily galvanically isolated from the right
For standardization they use an arrangement of 4 and 4 terminals, maybe for many models
You would want for yourself to do
3 and 5 pins?
Profitability, and easy technological process.
Dozens of brands make transformers with terminal arrangement depending on the scheme, layout
the wiring diagram does not relate to the actual mechanical order of the terminals

Hi!
I have sketched some possible configurations for you. All must work.
My favorites are A and E.
According to the theory the E variant should offer 2:1 ratio, but sometimes in practice things are a little different.
In version E you will have the DC ohmic resistance as follows:
Primary Rdc1=330ohm
Secondary Rdc2=60ohm
It must work very well.
(there are more functional variants, but these are enough)
Test all the sketched variants and choose the one that gives you the sound most to your taste.
Is it DIY enough?

Thank you micolas ! You're a real Boss ! Respect...

I will try "E" solution this afternoon and will do an A/B test with the original SC1100 I'ev got
BTW : may I ask you something... I had 2 broken X1S microphones... I set up 2 circuits (Schoeps + polarization) and bought an Ali capsule to test. The electronic circuit is ok. One of the 2 X1S capsules is ok. The Ali capsule (20€) is not bad at all ! The 2nd X1S capsule gives sound but when the acoustic pressure increases (I bring my voice closer to the microphone) the sound disappears... and it returns when I leave the capsule to rest for around twenty seconds...
Put the capsule with problems in a plastic bag with a zip (that can be closed hermetically) together with a few sachets of Silica Gel, (desiccant, Silica) and keep it for a few days. Try it after that.
And clean the input circuit (and not only) of the microphones with concentrated isopropyl alcohol very carefully.

what is the link for
Ali capsule (€20)?

tested this morning with the schoeps circuit : pretty balanced... and good gain
