These curves have nothing to do with grid current, Peter. Whenever grid
current flows in a grid driven amplifier, linearity is compromised. More
grid current equals more non-linearity.
- So far, the 'body of opinion' appears to consist of: Messrs. Chadwick
and Rauch. Are there others who say that more grid current equates with
less distortion in grid-driven service?.
