The 2200 ohm resistors go to the screen, same as the 470pF capacitor. The suppressor is internally connected to cathode.

Notice the screens are floating with a 470mmfd to ground. The suppressor has the 2200 ohm resistors to ground. With a floating screen, the plate will barely get a signal. I am going by the first schematic link on the W140 site. I have disconnected the screen on pentodes, signal and output, and the signal was greatly attenuated and distorted. The screens need to be at some negative voltage potential reference to ground and be less positive than the plate. If I am wrong, what did I miss?
