Conflicting information about tube placement in Mesa Fifty/Fifty poweramp...

Just received a pair of SED 6L6GCs from Dougtubes in the mail with the intention of re-tubing only channel A of my stereo Mesa poweramp. I only use it in mono operation so I figured that I would only need to replace two of the four tubes.

On The Boogie Board, there's a thread about this exact topic and I'm seeing all sorts of responses that it's configured AABB, BBAA, ABBA etc.

Here's the thread:

I don't know what to believe. Anyone here know for sure? I'm using the old version with the class-a switch.
