Having just finished one of these (the chassis is a couple feet away, let me tell you what you've got:
The 2 greens going to the tube filaments is probably right.
The red wires are the primaries, one goes to a bakelite capacitor block, one to a terminal very close to the bakelite block.
The red/black wire is the center tap of the high voltage secondary, and it goes to a candohm bias resistor (the long strip), assuming it's wired correctly.
There should be 4 wires going from the transformer to the rectifier, and NONE to the 41 audio output tubes. Two of them will be the high voltage secondary legs to the plates of the rectifier, and two will be filament voltage for the rectifier.
Personally, I would mark all the wires, pull the thing out and check the resistance of the windings to verify what wires are what, then figure out a safe way to verify the voltages.

It's not how bad you mess up, it's how well you can recover.
