Thanks! 

I wonder why they needed (wanted) such a large capacitor (1 MFD) from the screen grid of the last '24 tube to ground?

The center tapped wire wound resistor between the center tap and ground would carry all of what goes through the resistor you mentioned, plus other loads, so I wonder if it is adequate?
