Hi Lew,
I don't bother to look at waveforms such as you propose. My building is evaluated by ear, so I built a amp with provisions for both rectifier approaches, and heard what both ways sound like. I "was", at the start, in my theoretical mind, a dual rectifier guy, it had "half ther Z " etc.
But my EARS could not make out clearly the diction and enunciation, on my Gilbert and Sullivan operas, so I am back to one dual rectifier, not two. I have been told by my friend Dennis Fraker that this would be the case with a highly sensitive driver tube ( mu of 70 to 100 ) and he suggested to me to use the current production JJ 5U4GB, which is reasonable in cost at $16.00 and directly heated. Will give it a try next !! Two other people I know in DIY audio with high efficiency speakers, had my same listening - learning experience in 2013.
