Well, I think he mentioned that the PT is DESIGNED to run 6L6s as well but the pics clearly show 6V6s. Never said he wants to. All beside the point; there’s some DC coupling going on and one of the trannies should be reoriented.
the OT is already 90 degrees out of alignment with the PT in terms of both the iron stack and the bobbin wind
I don't believe that the photo above represents any of his configurations pictured,
...doesn't actually show the orientation @CirrusBand found to be quietest in his post 9...
