1941 Du Mont  Service Notes for "X" Series (28K bytes)     Service Notes for the 1941 "X" Series of Television sets (printed in 1942)

 

According to Steve McVoy, the pre-war Du Mont televisions used (4) different types of CRTs:

1)  114-9-T tube without intensifier
2)  114-9-T tube with intensifier connection on the side
3)  14AP4 tube with intensifier connection in the base
4)  K1003P4 tube as a postwar replacement

One of the toughest things to document are the differences between the various pre-war Du Mont sets.  Steve offers his explanation of these differences:

  •   The late 1938 early-1939 sets used the CRT without the intensifier. These are the Model 180-series, although Harry Poster refers to the table model as an 'Model 80' in his price guide.
     

  •    Mid 1939-1940 models 180, 181, 182, 183 are the same as above, except they have slightly different knob layout and use an intensifier CRT.
     

  •   The 1941 "X" Series -- Models 180X, 181X, 182X and 183X have a different knob arrangement, and include a special 'mode switch', so that the viewer can switch between the original 441-line and newly adopted 525-line systems.  Without this switch, the viewer would have to manually adjust the Horizontal Hold to lock-in the picture on the screen, if they were changing channels between a 441-line broadcast and a 525-line broadcast.
