[Amps] SB-220 bias question

[jerome schatten]

And by extension, consider an amplifier tuned with a steady tone for  
maximum power out when the i/p side of the pi network matches the tube  
plate Z and the output of the pi matches the load Z. If the amplifier  
was then used on SSB driven by a human voice, the only time the amp  
would _not_ be mis-tuned is when the human voice peak drove the amp to  
exactly the same level as the peak of the tone used for tun-up.

That seems wacky to me.
