The first one that comes to mind is the 5C3.

That one I have, but you would not know that because I was too stupid to mention the obvious.
But Thank You.
Guess I am looking for a Non-Fender schem if there is one. I know Red Iron uses Octals in the pre, but I do not know if they have the configuration I need.
Thanks Again

I'm working on one now with 2x6v6, a 6sn7 pi (yea i think i can get this to work) and some 6sj7s but i'm going for a switchable OD section, as well. I would be interested to look at what you dig up so please share if you dont mind

Is there a mistake in that drawing ?
Where does the first stage and the second half of the PI get B+ ?

I think there is a jump and a joint mixed up.
