nope

whatever you do with DC level in front of Edcor , there is Elna Silmic between Edcor and OS

Sorry, not making myself clear, What I mean to ask is the use of the 220uf that mark's design contemplates wont end dc at the speaker taps will it? The original pot from PAPA's schematic will have to bring that to zero, right? or No?

Yes. My understanding is that 220uF cap will just remove any DC at Edcor input. You still have to use the original pot to bring the offset down to zero at the output of the amp.
