    The tube listing above reflects the schematic rather than The Model 23 tube listing provided by United Reproducers at the 1929 RMA meeting.  There are two differences shown in the schematic:

    1.  A third 227 for an additional audio stage.

    2.  The addition of a 201A tube, referred to as a 'polarizer', which was required for the electrostatic speaker.
