曙光电子管厂探秘
为EL34B定位安装
装配EL34B
组装805
安装12AX7B灯丝
使用显微镜精确安装
300B全家福
进去后拣几个300之类的管子。
那叫偷！嘿嘿！就在俺家附近啊，现在冷清很多了！～～～
一直没有进过生产区正因为是手工产品,更要保持工作环境卫生干净,
你看那乌黑的手套,工手作台也是乌七八黑的,说实在的,在我修理电器的车间是那么宽敞明亮,干净整洁的,只是一般的工业电器而已.天津厂也是纯手工的
还在生产的电子管厂家国内好象没几家了.
电子管仍是半手工的产物。
所以发达国家通通地下马了。剩下的几个国家产量也不大。
很多厂家买曙光的管子打标，看中的就是曙光的成本低。咱们能玩胆，现在就靠曙光了，什么时候曙光的厂景达到了发达国家的程度，咱们的钞票也快玩不起胆了。
技术装备落后,工作环境状况糟糕
电子管这么精密的东东,就是在这样生产出来的?它发出的声音是否美妙很是让人怀疑.呵呵！MINI型的电阻点焊机，
这么小的我第一次看到！我买了曙光EL34B了
曙光的工艺能赶上70年代的西门子吗？

电子管，不像晶体管
都是些机械的东西，不能大规模的自动化。不象晶体管，在硅片上点两下就好了。电子管其实很简单，能生产电灯泡的厂就能生产电子二极管，三极管也能啊！因为灯泡是钨丝的，直热式电子管的阴极就是用钨做的，加个不锈钢罩，把灯丝照起来就是阳极了。哈哈！要是玻璃不绝缘，你直接在灯泡外加个罩，就是2极管了，哈哈！国人，，，很多方面首要问题不是硬件，，而是软件
说白了就是思想意识远比提高硬件水平更重要，，，就拿组装电子管来说，60、70年代的管比现在的管还好，为什么？是工艺水平？硬件水平？不是，只是因为那时候RP比现在好。
听说现在考驾照倒桩用上红外线精准定位仪了，有什么用？还不是关系硬的驾校顺利过关，关系不硬不软嘛，只好上10个刷5个喽。。。。
此言差矣！
