I don’t have the book in front of me but that is the PT that we use in the kit as well. 2A is plenty to run the filament supply, that does not draw that much current.
For the filament center tap, you will need to make an artificial one. For some reason, the new PTs removed the filament CT. This is done by attaching a 100Ω resistor from each green filament line to ground. I usually attach it at the 2 pilot light terminals and ground it at the 3 pin ground terminal. I’ve attached an image so you can see what that looks like.
The red/yellow is as described in the book.
