Since when were we talking about 8171s? We have specifically been talking
about the original G2DAF with a total of .007 microfarads. Even with .05
microfard, the tc is only 20 microseconds. Similarly, the 1500 volts doesn't
apply.

How is this different to voltage gain or power gain? If it is isn't, why
specify current gain as a particular parameter?
>This is true only when the grid circuit is not resonant.
How do you define resonance here? As the input in the G2DAF is untuned, your
XL = XC isn't applicable.
