请问6V6的工作点。

老豆

我的6V6单端工作点调整如下:屏压320（340），帘压220（235),栅负压－12（－14），屏流28mA(32mA).括号内是用旁热管整流的电压。请问是否合理？

老豆

您没用负反馈？我加了大慨9db的负反馈。

我比较喜欢用管子资料上的标准工作点
6V6的三个工作点:

1---180V          180V            29mA        3mA           8.5V         5K          2W               8%

2---250V           250V          45mA          4.5mA       12.5V        5K          4.5W            8%
