Default An other VBIGC question

Hello everbody,

I have an other question about the VBIGC.
I like the way it is set up but i do not much like the faqt that the output is 180 degrees out of fase.
I know that if i switch the + en - speaker wire this is fine.
But i have an idea about how to make it infase.
Look at the picture belowe.
In 1 you can see a normal valve buffer for the VBIGC.
In 2 you can see a valve buffer who should be 180 degrees out of fase.
So im thinking, if i put the IGC behind 2 the fase on the output of the amp wil be normal again.
Anyone ever tride this?
Is it true what im thinking or isn't this going to work?

Please give me some thoughts about this.

Default Fase should be Phase

Fase should be Phase of course.

Sorry about this.

switching between the common anode and the common cathode mode isn't so simple. Also, gain and output resistance are needlessly higher in the CC mode.
