I have Google translated your title and also added it to your first post.
Thank you.
McIntosh considers that a trade secret, and this is a very complex winding, but here is a video.
The OT winding starts at 2:15.

The only sure info i could gather is, that the primaries are bifilar wound with Formvar isolated wire, and that there is only 1 coil.
Formvar has the lowest Dk of any laquer based magnet wire isolation..
Anything else was conflicting info, triple or quadriple isolated Formvar? Shell type core or not? Afe? Number of turns? Interleaving?
A lot of conflicting info, its a mess...
It is possible that there are different variations of the same transformer.

Quite complicated, clandestine issue. Anyway, the OT design for sure depends on the MC 275 version. First, original amplifiers feature triple wound primaries, latter (and current?) designs made down with bifilar windings.
