If I was building this, I would leave the output transformers where they are and move the Inductor (Choke) and the Mains transformer over to the right. Keep the air gap of the Inductor (Choke) to the edge of the box.

Ya you are right this may reduce the EMF affection between the output and choke or main transformer. Bur the look of this will become a little odd.~~ But thanks for your ideas~

The general rule of thumb when placing inductive components tightly together is to orient the coils 90 deg from each other.

do you mean each of the transformer should shift 90 deg to each other?

Yes the coils should be 90 degrees in relation to each other.

That's correct for orientation, but the point was made that the choke should be in the corner not in the center and the same with the PT; so put them over on the left edge. If you are using a rectifier tube it can probably go between the two PS transformers. The output transformers will be between your highest EMF generators and your signal tubes which will be in the space to the right. Distance is everything with the EMF so put your PS as far as possible from your signal components; that's just basic good layout practice.

YA but i'm not quite sure the terms of PT PS transformers
And the highest EMF generator will be the Main power transformer~
