Oxymoron. Class C is NOT linear!

True
Now if you want to amplify CW or FM signals, class
C is fine. For AM or SSB signals you want class A, AB or B.
For this tube the grid #1 bias, grid #2 voltage and grid #1
drive (signal input) are different as you change class of
operation. (Mostly the screen and plate voltages can remain
the same and just change the resting plate current with the
bias and don't apply more than a specific signal level so
your max plate current isn't exceeded.)

Hi

Class C isn't fine.
Class C is producing a lot of harmonics
Specially odd ones are bad.
I don't recomment class C elsewhere but for transistor FM use in VHF and
UHF
Maybe also for KISS QRP in HF CW
