[Amps] Cold testing cathode driven GG input circuit

[Conrad PA5Y]

I know how to cold test an anode circuit by connecting a resistor 
between anode and grid using a resistor with the value of the design 
plate RL. I presume that I can do the same cold test for the input by 
using a resistor of the value of cathode Z in. Its a 3CX800A7 is 
supposedly 54 ohms for my design parameters. I am assuming that if I 
connect a resistor of this value between the cathode and grid I can do 
exactly the same thing as for the anode?

Is this correct or did I miss something?
