<p>收藏学习，什么时候能自己搭个电路测特性曲线就好了，hoho</p>

&nbsp;&nbsp;&nbsp; 请问，电子管参数测试仪绘制阳极曲线，阳栅曲线，转移特性曲线做交、直流负载线选择工作点，对正确使用电子管，特别是非音频放大用途的电子管移植到音频放大使用是很有用的东西。但是栅负压阳极电压都是分档调整（电池的个数），达不到无级调压。另外，阳极电压一般是300－500V甚至有的要达到1000V，用多少各电池才能达到？胆管灯丝低电压达电流6.3V 4A的电流要多少各电池并联？

    很好的资料，照单全收 本着学习的精神，个人认为，要用电池来测试电子管的特性并绘制曲线很不现实，一则电池容量有限，二则电池用时间长了以后内阻增加，影响测试精度，我看到过很多本地玩友自己制作电子管动态测试仪，配合信号发生器和示波器，能绘制很好的实际动态曲线，对业余制作选管很有帮助，有些放大管可以直接上机进行测试，而且简单易行，测试手段因地制宜，对于一般配对选管很有效果。
   以上意见仅供参考。
