The 6W6 works really well in SE mode in the Marblewood Amp (more information here: https://www.cascadetubes.com/the-6v6-marblewood-amp/).

Concerning the schematic you posted, the voltages are based on the transformer used (300-0-300) at load. My guess would be a B+ around 350vdc at load. The screens are held lower by the 3kΩ dropping resistor. Personally, I'd run the tubes in UL mode with a higher bias voltage (i.e. larger self bias resistor). In my opinion UL mode always beats pentode mode. YMMV
