As Ed VA3ES had mentioned earlier in the thread, 

 

All the data you're looking for on the Hammond 2300 series of modulation transformers is available at the va3nth.com/shortskip site in the downloads section. Lots of other information on the older Hammond modulation and driver transformers too.

For the terminal connections and the impedance ratio tables.
