Hi,> but how much current must the c3g draw?
10mA.
> the powerstage is already finisht it is a fixed bias
> stage i wil do 400 volt on the anode and 80ma currentYou may find that in this case the C3g will be VERY magrinal to drive the power stage with 1.6V input, unless you add a stepup transformer either after the C3g stage (1:2 stepup interstage transformer) or before (1:2 lineinput- or auto- transformer).
The C3g can swing enough voltage but is a little short of gain.
For your circuit the D3a might be a better choice, with more gain.
