The second stage needs to see +75V at its grid, and Broskie has added in the two 1M resistors and coupling cap to provide this.
If you adjust the operating point of the first stage you can change the voltage at the plate from 150 to 75, then this plate can be connected to the grid of the next stage (leaving the 300 Ohm resistor to prevent oscillations).
To make this change, you'd want to draw some load lines. I'd recommend looking at 47K and 75K.
