•  The components identified by 

[  in this basic schematic

    diagram have been carefully factory-selected for each set
    in order to satisfy regulations regarding X-ray radiation.
   Should replacement be required, replace only with the
      value originally used.
•    When replacing components identified by

,

 make the necessary

      adjustments by using RV904 (

[) as indicated.   (See page 14)

•   All variable and adjustable resistors have characteristic curve B,
      unless otherwise noted.
