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.
