This photo probably shows it best.
At the top right you can see the dual switch arrangement which you can read about in the link below. You don't have to use this idea but the photo shows that I connect the thermistor from one of the switches to one of the 110 vac terminals of a 12.6 ac transformer. The 110 vac terminals are also connected via the thick black wire(s) to the red wires feeding the AC unit.
The 12.6 vac transformer is used to power the PCB circuit that provides DC to the 6SK17-v tubes. The input terminals are just convenient to use.
I hope that helps and I trust your wiring is much neater than mine.

Wow, what a heap of hardware! Why do you need so many? I think I will try mine without the thermistor first and see what happens. Thanks!
Each smps module delivers 48 vdc and I stack them with the grounds not connected. 12 x 48 = 596. 4 x -48 = -192. See link below for where I got the idea from.
Most of my amps become too complicated since I like to combine ideas that other people come up with. Sometimes the ideas produce decent sound, sometimes not,but I learn by trying. From what I can see, you are doing much the same thing.

Roger on that. It's the most fun too!
