In Reply to: RE: Agree - "grid resistor" - but then again... posted by Triode_Kingdom on January 16, 2022 at 11:28:23
The problem is newbies arent about nuances of expression juggling by experts. They see a resistor going directly to the grid so think people are talking about this when they refer to "grid resistor". You have to go back in thinking to the time you didnt know what the differently positioned resistors were about and then consider how to talk about them so the ignorant dont mix things up. Because they do mix them up which is the point! Not which expert uses the cleverest name.
Follow Ups:
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.
