BMK2 used in cathode-biased amp

[Champ81]

Thank you. I think I'm beginning to understand this a bit better now.

1) A cathode biased amp is where the grid (effectively is grounded) is negative relative to the cathode resistor which sets the idle current depending on the resistance of the cathode.

2) A fixed biased amp is where the grid is negative through an applied negative voltage while the cathode is grounded. So the grid is negative relative to the cathode through an applied voltage to the grid.  

Am I correct to deduce that in both cathode and fixed bias the grid is always negative relative to the cathode. Where in cathode bias the grid is passively negative relative to the cathode depending on the cathode resistance. While in fixed the grid is actively negative through the grid leak network.

So in both situations they are cathode centric. But in cathode bias the cathode resistance is "actively" setting the bias condition. Where in fixed its the grid "actively" setting the bias condition. But both relative to the cathode.
