Re: Bias Resistor Increase = lower gain?
That’s the reason I have 275-0-275 HT colossal,not to simulate colin’s amp or the 1974X but to get the sweet spot B+ with the higher wall voltage.

Re: Bias Resistor Increase = lower gain?
I just mention that because the 1974X diverges from what we consider the 18W Lite foundation. I will be interested to see what Junior Marbles reports for his cathode voltage in his 1974X with the stated conditions.

Re: Bias Resistor Increase = lower gain?
Just going back to the question in the thread title,No, since the power tube cathode resistor is bypassed with a cap, the resistor's value will have virtually no effect on gain.
