Boy are you thorough! Nice work.

Changing the topic slightly, how much drive does a GS-35b need for 
1500 watts output? It's probably on the web somewhere but I've looked 
and can't find it. The comparison chart between it and the 8877 shows 
a ~2dB difference in gain but no actual drive numbers. I could figure 
it in reverse but I'd like to hear from someone with actual experience.
