As far as I know, the Williamson output stage has the screen grids of the pushpull tubes tapped down on the output transformer to give triode-like characteristics while keeping high plate-efficiency. I think its an idea from the 1950's hi-fi era.

The phase inverter of the 41-290 is a much better circuit than that of the 41-280. Is it a Williamson phase inverter?
