Enzo,  
 
Can you help me understand your response in relation to this article?

If I understand what I read, Rk, the cathode-biasing resistor, is used to develop the biasing voltage on the cathode, but without Ck, (AC BYPASS) the bias voltage will vary with ac input signals. Is it that Ck's influence on bias is so subtle as to not generally be considered a factor in establishing bias?  
 
Thanks,  
Craig
