I assume you mean above the 1 ohm resistor.
At the X, it is ground all the time.
Mimimum .04V and max of .06mA for Class A1.
You are able to go class A2 (grid current).
So .07V will give you 68% duty on the 211
which is good for longevity.
.1V is the absolute max for the 211
which will shorten lifespan alot.
The higher the bias voltage, the more power
but will lower the 211 lifespan.
The trade-off.
I would start at .06V and see
if you have enough power.
If you have plenty of power then good.
If not, increase until you do.DanL
