For those men who are interested in the construction of v -t voltmeters, adequate information will be found for v -t voltmeters were built in the author's laboratory, and constants are given for the components of many types, as well as a wealth of other useful data. These and their uses are explained, as is the calibration of the different types. Like nearly all types of voltmeters, multipliers and shunts are employed with vacuum -tube voltmeters to extend their ranges. Not only is the theory explained upon which the functioning of the different types of v -t voltmeters is based, but the practical applications of these instruments are completely described. Here is a book that is a perfect mine of information for everybody who wants to know all about these important instruments. By its proper use, dynamic measurements can be made under any and all conditions with minimum of effort and time. $3.50 VACUUM TUBE VOLTMETERS The vacuum -tube voltmeter has been rapidly forging to the front as a favorite tool of engineers, research workers and servicemen.

It is free of every limitation which in the past has hindered speedy service operations. founded upon the signal itself, is the most basic, most fundamental method of trouble shooting ever devised. Television receivers, facsimile receivers and other systems in- tended for special application can be serviced with equal ease. Every public address system, every centralized radio system comes within the capabilities of signal tracing. 744 S BOUND IN BUCKRAM $6 00 SERVICING BY SIGNAL TRACING Signal Tracing is destined to become the universally adopted method of locating defects in communication systems, no matter what the nature of the system-if it is a home broadcast receiver, auto -radio receiver, police receiver, commercial, marine, navy or army receiver. Chapter IV-ANALYSIS OF RCA RP -152-C RECORD CHANGER. x 11 paper, the same size as Rider Manuals, the book covers, by means of explanatory text, mechanical and electrical diagrams, all the information you must have to service these high cost instruments quickly and profitably. Hence the birth of Automatic Record Changers and Recorders. However, with the introduction of the automatic record changer, some knowledge of the development of motion by means of gears, levers and cams has be- come necessary. Mechanics in radio receivers was limited to a lesser degree. Heretofore, the serviceman's prime interest has revolved around the invisible defects which accompany the operation of electrical devices. Rider anticipated this need and has prepared-just when you need it-a sturdily bound volume containing everything you need know on any automatic record changer or recorder coming to your shop. 2 ae E2t' RIDER'S "Automatic Record Changers and Recorders" 800,000 record changers are providing an important source of profit for the wide-awake service shops of the country and creating a need for adequate and ready reference data to speed up trouble shooting and repair.
