Rider New applications of the cathode-ray tube require that the 1939 serviceman know more about its operation, characteristics and performance. The cathode-ray tube as the principal factor in television receiving sets is but one of the applications with which you will soon be faced. Use of the Oscillograph in industry is increasing every day in testing vibration, strength, engine pressure, etc. Industrial users need servicemen to maintain their oscillographs.

The importance of correct antenna installation and television receiver placement was emphasized by M. B. Sleeper, district sales manager. Because of highly individualized reception conditions, no definite rules were stated for the "perfect antenna installation". Servicemen were urged to give careful consideration and sufficient time to this problem. Good, intelligent workmanship can command a better return in the television field, said Mr. Sleeper because of the greater cost of the serviced article. Andrea will offer basic technical training to the metropolitan serviceman under two plans. First plan consists of a course of six lecture-demonstrations on the construction of a television receiver. The second plan calls for the serviceman to construct his own kit under technical supervision at the same six-session lecture course.
