I guess we can start with the 75TL, 100TL, 250TL, 304TL, 450TL and go
from there. At least that is what Bill Orr says about TRIODES in AB2 or
AB1 grid driven service way back in a 1965 CQ article.  I built and ran a
pair of 100TL's on 6M SSB back in 1964 or so. Ran fine, sounded good.  If
I had the desire, which I dont, to build an AB2 grid driven beast today I
would dig into the spec sheets. 
 
Since I have neither the desire or time to play word games I will leave
the design details up to you.
