stEH Licensed Under U. S. Patents of Western Electric Co., Inc. PD-50 SERIES AMPLIFIER The circuit design of the "PD-50" series amplifier incorporates all the latest recognized developments essential for highest quality, brilliant, true life-like reproduction. Foremost of the many unusual built-in features is the complete complement of "Climatite" treated transformers and chokes, recognized throughout the world for their ability to stand up under most severe operating conditions, they have been found to be unusually free from trouble under extremely humid tropical conditions . . . Plug-in type filter condensers make replacements of these condensers as simple as changing a tube . . . Calibrated step-type volume control . . . Instantaneous silent change-over in photo-electric cell circuit . . . Photo-electric cell connections through low capacity cable with heavy locking connectors to amplifier . . . Wide range tone control . . . Built-in booth monitor and monitor amplifier assures ample volume OS;, monitor . . . True, life-like humless reproduction . . Maximum safety factor . . . Complete amplifier chassis quickly and easily removed from cabinet and extra chassis is available for theatres wishing stand-by protection . . . Available as au accessory is a remote volume control and changeover, for operation from the working side of the Number Two projector. 15 POINTS OF QUALITY • 1.

MORE THAN AN AMPLIFIER Remote Volume Control and Change Over Brings complete sound control to the working side of each projector. A MIRACLE OF TROUBLEFREE OPERATION PLUG-IN CONDENSERS Make condenser changing as easy as putting in a tube . . . no wasted time . . . no wasted effort. One look at the workmanship in this amplifier is enough to convince even the most critical — — — user of the high quality of Sound Master equipment. TIME PROVEN AND PERFORMANCE TESTED THE BALLANTYNE COMPANY 1707-11 Davenport St. Omaha 2, Nebraska, USA Export Department, Frazar & Hansen, 301 Clay St. San Francisco 11, USA Cable Address "FRASEN" program in good time would help substantially to supply needed jobs. Mr. Eberson indicated his belief that jobs would soon be our biggest problem. The Government's own figures tend to support this. Here they are from a document entitled "The War— Phase Two," issued last month by the Office of War Mobilization and Reconversion." "During the next six months, probably about 1^2 million workers will lose their jobs. A larger number than this will be out of war work, but they will continue in the same jobs, producing for civilian consumption. Also, in the next year, about 2,000,000 men are expected to be demobilized from the Army. During the following six months, perhaps another three million workers will lose their jobs." That adds up to six and a half million men looking for jobs during the next twelve months. And the same document places present unemployment at about one million. Write Us If You Want To See Boester's Plan SOME of those responding to our suggestion in the May 26th issue to tell Carl Boester to go ahead with his scheme for a small theatre, indicated that they thought his proposed plan concerned air-conditioning. Carl's many contributions to these pages have been devoted to air-conditioning, ventilation, etc.; however, the plan he has in mind, so far as he has divulged it to us, embraces the form of the building, and the materials and method of construction. As director of housing research at Purdue University, he has been investigating construction methods and new materials, so that his work has taken him far beyond air-conditioning for a number of years. For those who may have missed our suggestion, we repeat that Carl has been having, as he wrote us, "a hell of a lot of fun imagineering" how he would build a 500 or 750-seat theatre. And at least he thinks he has found out. "It wouldn't be very close to anything you now use or are familiar with," he wrote, "but I think I could justify everything recommended from the point of view of air and seating comfort, safety and convenience, to say nothing of good sound and good vision." But, said he, it wouldn't be worthwhile to develop an actual working plan unless a large number of exhibitors were interested in seeing what he had up his sleeve. So we suggested that readers who were interested tell us to tell him to go ahead. Many have, but Carl wants a flood of communications to indicate widespread interest. Just say, "Okay, Boester" on a penny postcard, address it to Better Theatres, 1270 Sixth Avenue, New York 20, N. Y., and we'll do the rest. 6 BETTER THEATRES, JUNE 23, 1945
