看了本刊2000年第4期第41页夏洪文先生“长虹C2591系列彩电末级视放集成块代换”文章,夏先生用以末级视放管为核心元件组成的分立元件末级视放电路修补原机故障末级视放集成电路的方法很好,构思巧妙,实用有效。但笔者认为用2SC1815型号三极管作为彩电末级视放管是错误的,应该给予纠正,否 Read the magazine No. 4, 2000 page 41 Mr. Xia Hongwen “Changhong C2591 series color TV final-stage video integrated block substitution” article, Mr. Xia to the final stage as the core components of the discrete components of the last component The circuit repair the original machine fault the last stage put the integrated circuit approach is good, clever idea, practical and effective. However, I believe that with the 2SC1815 transistor as the final color TV tube is wrong, it should be given to correct or not
