<< The grid choke is a substitute for a grid resistor. the TX valves I like call for a low grid circuit resistance. For example the 813 maximum g1 resistance is only 30kOhm. The low DCR/high AC impedance of the choke seems to deal with small grid current production far better than an ohmic device. >>
I don't think I worded my post right. What I meant was putting a plate choke or a ccs on g2. Thereby replacing the 470ohm resistor in the above schematic. Thanks for your help Doug.
