  The tube listing above reflects the schematic rather than The Model 21 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.  When a unit was  Kylectron-equipped, a 201A was added as a rectfier for this electrostatic speaker. The 201A was not included in units with dynamic speakers.
