This is the data sheet for the transformer....yellow and black connected together to provide the 24v supply across orange and red to the 24vdc rectifier, connecting red and black (12v) to the 6vdc rectifier.....sounds straightforward enough 818By9byH9L._SL1500_

timestamp is a bit of a challenge here......my replies are all jumbled up, however wired up the transformer and powered up....slowly with the variac and watched the output of the 6vdc regulator it came up nicely.....and as i wound up the variac the output started to fall back to 0vdc....like a capacitor charging up?
This is how it looks, I have the regulator connected on leads to allow measurments to be taken easily
This is the regulator 6vdc output under operating load
