Grid-stop resistor goes right ON the grid pin, with nothing else connected to the grid pin.
There is a good theoretical argument for dumping the Rk bypass capacitor in SRPP. You might want to try it. It equalizes current flow around the circuit. This is assuming that Rk1 = Rk2, where Rk1 is the cathode resistor on the lower tube section, and Rk2 is the resistor between the plate of the lower tube and the cathode of the upper.
