Wright Mono 8 Schematic & Operating Points

Does anyone have operating points or, even better, a schematic for the George Wright Mono 8 300B SET?

I'm currently developing a 300B SET inspired by his WPA 3.5 circuit, which is the same as the Mono 8 but for a 2A3. Mine would use the Magnequest TFA-204 (3K, 60mA), so I'll probably run the 300B at the 350Vak/60mA op point. But I'm curious as to how George set up the 300B for the larger FS-030 and more specifically the 6SN7 input stage.

I imagine the input stage is not much different from the WPA 3.5 but it would be good to know.
