UAX13 Diagrams This page is going to be quite a sizable one! The U13 was around until 1996, and so has had many modifications to its circuits over the years. I have also listed copies of the Engineering Instructions that are relevant to the U13. Note the where the diagram numbers have an 'n' after them, the link takes you to the diagram notes.
