In Reply to: RE: Cathode bypass cap removed and I like it posted by banpuku on January 10, 2017 at 15:12:10
Removing the resistor will cause the amplifier to cease operating. There won't be a current path through the tube.

Thanks. Should the resistor value stay at 1K or be changed up/down?
Don't change the value of the resistor unless the bias current is incorrect. You could try different types of resistors, though.

Bias is DC.
The bypass capacitor prevents AC from forming across the cathode resistor when the tube is feed signal. This prevents the local current feedback that would otherwise occur.
The DC condition does not change when the bypass cap is removed so there is no reason to change the cathode resistor value.
