So you need five connections and six isn't extraordinary. My replacement transformer actually has two 0-115 primaries for 230V rather than a centre tap, so they can be in parallel on 110-120 mains.
Here's a photo of the Tx. I'm just trying to work out which is which, how to illustrate this on a drawing. I will need to mark everything up to test to determine windings, tappings etc, but I probably won't be able to go that far tonight.
The caps to the left of pin 1 are just using the Tx for support, but not connected at that point, but they are connected to pin 4.

I am still working on the drawing of the sig gen. Thanks for your help so far.
