Very similar, I had a 100H choke to ground using one 1/2 of the tube. The B+ was 950V, dual power transformers.
I think I would use a switching supply for the 10V filament these days. Even though in spec I did have a few CAPS in the first proto blow because of the inrush current of that damn filament.
