Hi I see you have set the tubes in full class a.
The current is nearly as large as the total power of the tube.
I had a bit of the data translated from Russian and saw that there are about 3 mA (270mV) at rest.
I also had a schematic with the preference for class b
with a negative grid voltage (this shouldn't be a problem the tube is capable of running at 150 v max).
And without the capacitor (it can slow down the tube a lot
and create compression).
Because it's a HF tube it's better to limit the hf with a capacitor(250v) and a resistor (the induction on this point can create a voltage of 240v)
I must say that I have not tested it.
By the way, thanks for the effort.
I'm still in a move but get to work with it as soon as possible.[/img]
