In an entirely new approach to testing horizontal-deflection amplifiers, the tubes are tested in circuits that closely simulate actual operating conditions. Six separate tests have been replaced by a single test. Carefully controlled test conditions and the development of several unique detectors for these tests have resulted in repeatable and reproducible results. Although the circuits have become more complex as a result of simplifying the testing procedures, cost of over-all testing has been reduced and product quality has been improved.","PeriodicalId":136909,"journal":{"name":"Ire Transactions on Broadcast and Television Receivers","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1962-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126643662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Another advantage of low tracking force is the reduction in wavelength loss. Two factors tend to place a limit on the minimum tracking force which can be used. One is the mechanical impedance of the pickup and the other is the stability of the pickup-tone arm system when subjected to jarring. Tracking force of approximately 2 grams is usual in high-priced manual players which are handled carefully by relatively skilled people. However, in most home phonographs tracking force is found to be above 6 gms. to insure stability when subjected to vibration. This paper describes a tone arm configuration which was developed to allow tracking at 2 grams in automatic record changers with a low mechanical impedance pickup described in a companion paper. As an additional benefit the new tone arm protects records by preventing damage due to accidental scratching or dropping of the tone arm.","PeriodicalId":136909,"journal":{"name":"Ire Transactions on Broadcast and Television Receivers","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1962-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131264233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
