Well it wouldn't be a:
then, would it?PIECE DE RESISTANCE
dhaen said:1)You have a constant voltage load in the cathode of your driver. Where's the signal going to go?
Explain further. Do I need a resistive load above the gas tube?
2) The idea of the cathode choke was to get rid of the very lossy resistor in the cathode. You've still got one!
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.
Joel,Explain further. Do I need a resistive load above the gas tube?
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.
Yes, that's true. But you're wasting power, both mains and speaker power with this scheme. Also, the choke won't work properly with a resistor in series.I need to bias the output tubes

Why is that?

Because it can produce some really enjoyable listening.
Sy, have a look at the end of this thread, it gives a hint...And it's still beyond me why anyone would go SE in the forst place

Cheers,
The resistor was in series with the energy being recovered from the choke; low efficiency.Although I still want to know why you cannot use the choke as the load in series with a resistor as Rk. John, care to comment?
