Yes we are talking about the same transformer feeding the 6L6 output tubes. It is a phase inverter feeding the push-pull outputs. Try reversing one of the secondary windings connections. If that clears it up, you're done. If not, put it back the way it was and reverse the other secondary winding connections.

Let us know it that does it.
