|[AMRadio] Biasing a Class C modulated final|

I am building a 2x813 class C final modulated by 2x813.
The typical way to bias the class C final is with a combination of
fixed bias applied to the control grid and bias derived from the rf
drive through a grid resistor.
Rather than fixed bias applied to the grid it seems that I could
achieve the same effect by using a pseudo zener in series with the
cathode, similar to what is used in cathode driven linears.
Any thoughts on this approach?
