Default Real McTube Help

I am tyring to build the Real McTube. I am confused on the wiring of the two transformers. Do I take the two output sides (the thin wires) of the transformers and connect them together? Does the second transformer actual connect before or after the diodes and filtering capacitor? I'm hoping the picture helps. Transformers still confuse me. Will someone who has built one, share a picture or two of the power supply portion?

Thanks.

They are hooked secondary-to-secondary.

I have built one. You really have to understand what you are doing, the 12v or 6v output of the first transformer goes to the 12v or 6v(don't know what transformer are you using) output of the second one. The primary(thick wire) from the second transformer is then rectified and filtered and then you got your B+. After that you need your filament voltage, you can wire them parallel(will need 12V) or in series if you're using a 6V transformer; so solder 2 wires from the output of the first transforments to pin 4 and 5 of the valve socket(parallel connection) or one wire to pin 4 and 5 and the other to pin 9(serires connection)
