Take a 6sn7
250 volt plate
22k plate resistor
8ma.
About 1k bypassed cathode resistor
Gain 14, DB gain 22.9
Now take a 6sn7
250 volts plate
11k plate resistor
8ma.
about a 1K bypassed cathode resistor
Gain of 11.25, DB gain of 21
That's a gain difference of 1.9db.
That's not enough to make any real difference if he's fighting a situation of "too much gain" but the harmonic distortion will be much higher with a 11k plate resistor vs. a 22k plate resistor.
Am I missing something?
