I'm having trouble too.
Why is the grid resistor 1 meg?
You could get two 1000pf (.001uf) and two 500pf (.0005uf)
Place one 1000pf in parallel with one 500pf. That would be one .0015uf cap and that will work.
Against the 1meg grid resistor it would make a 6db per octave high pass filter with a -3db point of 106Hz.
