How many of these sets have you got?
The diagram you posted shows the screen grid of the 6K7 fed from a potential divider comprising 68k from the HT rail and R11 (value not stated) to ground.
No trace of the 47k resistor you mention in your last post.
Edit: Just re-read the thread and post #5 in particular.
