Well, after some suggestions, this is what I've got so far. How is this looking?

1) You have a constant voltage load in the cathode of your driver. Where's the signal going to go?
2) The idea of the cathode choke was to get rid of the very lossy resistor in the cathode. You've still got one! No wonder our banter about cathode chokes made no sense..

Default PIECE DE RESISTANCE

Hi John,

Since no value is specified it could a 0 Ohm jumper?

Cheers,

Explain further. Do I need a resistive load above the gas tube?

I need to bias the output tubes, and the point of the choke is to replace RL, not Rk... and in that capacity it's keeping another 30 watts out of the chassis.

3) Lose the attitude.

Hi,

Joel,I don't think that OD3 is going to put out 150V all by it self.

Cheers,

Joel,
The constant voltage of the gass tube is exactly the opposite of what you want. If you want to be "smart", add a constant current source.
Gas tubes are good in common cathode. Not in cathode follower mode.
