Jeff -
you helped design a great power transformer with heyboer. they were able to add 2.5V center tapped filament to the secondary for me... they're actually nicely priced for such a robust massive transformer.
I think the design could be revisited with sony6060s idea of using M6 and shrinking the monster down.
in my opinion you got some of these things right "the first time", the heyboer power transformer being one of them.
those hammond 159ZA are great chokes BTW - I've had them as the first element after the rectifiers with over 80mA and no buzzing.
