OK, I followed the paths of the wires from the bad transformer as follows:
2 green- filament ones, no issues.
2 black going to the rectifier, seems pretty easy.
1 black going to a 41 output tube pin and 1(yellow?) going to tube 41 also.
1 red to a chassis terminal block -is this a primary?
1 red to the block where the ac lines are attached, is this a primary also?
1 red/black wire to a long bar strip at the top of the chassis.

I am trying to match these to the replacement 400 volt transformer that I have. It also has 9 wires. The primarys are marked so that is fine, the filaments are green and that is fine, there are also 2 yellow ones, I assume this is the rectifier, so that is fine, the area where I am not sure is the 3 other wires grouped together, one has a black magic marker dot marked on it. These are the High voltage wires, I assume.

Any assistance matching these wires would be a great help. The color is faded on all these cloth wires.
