为节约能源,提高音质,降低成本,满足人民日益增长的物质和文化生活的需要,国家广播电视工业总局于去年向全国收音机工厂下达了“关于加快研制优质、节能、低成本的台式晶体管收音机”的任务。经过半年多的努力,全国共有18个省市、49个厂家研制出62种型号的晶体管台式收音机120台,经四机部三所统一测试和试听,并与同类型号的电子管收音机(红灯711-3)进行了对比分析。测试结果表明,在电声性能上有27种型号(占43.5%)的晶体管收音机达到了电子管收音机的水平;有11种(占17.7%)样机音质较好,其中有5种接近电子管收音机的音质水平,它们是:红灯711-2B、杭州JTD-2、
In order to save energy, improve sound quality, reduce costs and satisfy the people’s growing material and cultural needs, the State Administration of Radio, Film and Television issued the “Radio on Benchtop Transistors for Accelerating the Development of High Quality, Energy Saving and Low Cost” to the National Radio Factory last year. The task. After more than six months of hard work, a total of 120 models of transistor desktop radios have been developed in 18 provinces and 49 manufacturers across the country. The four machineries are tested and audited by three uniforms and tested with the same type of tube radio (red light 711 -3) conducted a comparative analysis. Test results show that there are 27 models (43.5%) of the transistor radios have reached the level of the tube radios in terms of electroacoustic performance; 11 kinds (17.7%) of the samples have better sound quality, of which 5 are close to the tube radios Level, they are: red light 711-2B, Hangzhou JTD-2,
