[Amps] drive power

[Steve Flood]

Perhaps I was getting lost or misinterpreting this information from Tom, 
W8JI:

http://www.w8ji.com/loading_amplifier.htm

When I read this I conclude that my exciter (TS-870S) should be run to full 
100w output to the amp to avoid "ALC overshoot" and tuning/loading problems. 
Based on the responses so far, I can either 1) reduce my exciter drive 
level, or 2) run the full 100w output but swamp the amp input down to the 
needed input drive level.
