I'm guessing 90% modulation is hard to distinguish from 99% mod on the air...

> I think it's theoretically possible only if you also modulate the signal driving the 4-1000A cathode circuit, and in the correct phase, of course. Otherwise the "feed-through power," which is a considerable fraction of the total output from a grounded-grid stage, won't be modulated and you'll never be able to get 100%.
