Because roughly 250v-min. on the anode is what you have to work with.
If you attempt to go lower that c. 250v, you make IMD go up. If you go
for more than 250v, P goes down.

yes
>More P than plate V*I => Lower Z than plate V/I.

>Am I right?
? I have no idea what "Source I" is.

? Up to about 200kHz, it is possible to construct a grid-driven
neutralized, triode amplifier, providing you use a triode with a Mu of 5
- maximum. .
