      Garey Barrell, who is a very frequent contributor to
      this list, publishes several CDs with very extensive
      information on Drake equipment. He has stuff there you will
      not find elsewhere. I very strongly recommend obtaining them
      if you are working on any Drake stuff. His 4C one will have
      all the variations on the schematics plus photos. See:
      www.k4oah.com They are not expensive.
