IT Transformer connection phasing

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Would this be considered in phase or out of phase.
I used a audionote schematic as a guideline to connecting a Hammond 126b IT transformer.
On the following transformer
Brown=B+
Blue=Input
Black=Ground
Green=Output to grid
I believe the schematic was wrong and the green should be ground or
Brown=Input
Blue=B+
Black=Ground
Green=Output to grid
I have my amp apart or otherwise I would just check it with a scope.
This is bifilar so I understand if connected out of phase, then capacitance forms part of the coupling which can limit the high frequency response. Many schematics show the connection this way but don't think all ITs are bifilar or the designer overlooks or draws it for simplicity.
