Can anyone give me an explanation of how cathode biasing becomes self-biasing? I understand how cathode biasing works...the current running through the cathode resistor creates a voltage which is negative relative to the grid voltage.
What I don't understand is how tubes of different types with different currents can be self-biasing. It seems like the more current flowing through the tube the greater the negative bias voltage would become. I'm confused....
Thanks For Any Input!,
