In Reply to: RE: Agree - "grid resistor" - but then again... posted by Paul Barker on January 16, 2022 at 23:14:30
A grid resistor implies fundamentally different functionality than a grid leak resistor. Skewing the meaning of technical terminology to suit those who don't understand it does everyone a disservice.

For those that read this post looking for some help here it is..
In cathode bias a small value resistor is placed between the cathode and the ground so it develops negative voltage on the cathode thus achieving bias. In fixed bias a separate circuit provides negative voltage to the grid of the power tube and the cathode is simply grounded.
In cathode bias a small value resistor is placed between the cathode and the ground so it develops ***positive*** voltage on the cathode thus achieving bias. The grid is at zero volts DC and the cathode is at a positive voltage so the grid is negative with regard to the cathode. That is what bias is, the grid being negative vs. the cathode.
