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. http://www.va3nth.com/shortskip/downloads.php?cat_id=7&download_id=35 http://www.va3nth.com/shortskip/downloads.php?cat_id=7&download_id=34 For the terminal connections and the impedance ratio tables.
