then what's the point of doing reverse winding for the secondary in a dual coils, humbucking configured Tx like the neve input if not for that ?
RW is a necessity in humbuck configuration, so external fields cancel and internal fields add up.
Thx for the schem, abbey.
About the RW in humbucking configuration, I think there is a misunderstanding about what I meant. I was talking about RW inside each coil (for example with a structure P-S like in neve input) and not the fact that the first spool has to be wounded clockwise for example and the other anticlockwise (or we can flip the second spool/coil, right ?) to be in an humbuck config. just like with guitar pickup.
Here is a post about St Ives/Marinair neve input Tx and the difference was that StIves Tx didn't have the reverse winding.

I don't think the OT meant that StIves trannies aren't in humbuck config (it would be weird since they aren't mu-shielded and a simple flip of the 2d coil would make them in humbuck config ) but he probably wanted to say that each coil didn't have 1 or more layers reverse wounded vis-a-vis the other layers of the same coil. Anyway that's what I understood but I could be wrong....
