First, it is drawn that the two 6.3 v secondaries are connected out of phase.
Then you have a bridge rectified 6.39 volt DC connected to a 28 volt reference on the positive end and ground on the other. This does not work and has to be drawn wrong.

You raise a DC supply by referencing the ground side to the elevated voltage.

If it was build like the drawing, you have some opportunities for improvement.
