- Notes
- The Zenith family X733 has been made with and without clock. This we state according to Beitman Volume R-16, where you find the words: "The Material below and on the adjacent page at right is exact for Model T723, Chassis 7T04. This material also may be used for servicing Models T724, Y724G, R, W; Y723-G, R, W, Chassis 7T02, 7Y02, 7Y04, which are similar; Models X733G, R, Y; Y733G, Y, R, Chassis 7X03 and 7Y03, are also very similar." The section Diagram for chassis 7X03 with measures for a clock is for the models X733G, X733Rand X733Y.
SAMS Photofact shows three same looking families, the X733, the Y733 and the Z733, all with alarm clock and only the picture shows little differences between each other: Y (See SAMS set 339, folder 17, Dec. 1956) indicates the 3 knob functions for the clock within the Dial, Y not, but both have a sleep function (top knob), Z733 (See SAMS set 339, folder 17, Dec. 1956) misses this top knob and probably the sleep function. The SAMS index refers to the same document as for Y and lists Z733G, Z733R and Z733Y (chassis 7Y03Z) but the pages do not show any trace of a Z. We may believe that it is the same model without sleep function - for a cheaper price. The suffixes G (light gray), R (brownish red) and Y (black) are used for the colors.
