One word: Distortion. When the voltage on the plates drops below the voltage 
on the screens, things start getting strange. Maybe that's part of the reason 
he's getting that assymetry. Makes me want to try something similar on my dual 
6146 AM transmitter. :) It's problem is that it reaches -100% long before it 
reaches +100.

I have pics and a schematic, there.
