请教！请提供一个胆前级！

翻了一下元件库，还有6n3 2个，6n4 2个，6j1 4个，6p3p 2个，f u19  2个。想利用这些东西做一个前级，要求中音要好，低音饱满，高音不刺，请大虾们推荐一个电路图，有板子最好！
学生有礼了！

图1：m7。图2：一级共阴放大 图3：srpp

好像同“我会建议用6N3，一级共阴放大加一级阴极输出。“的建议有出入。哪个更能接近“要求中音要好，低音饱满，高音不刺，请大虾们推荐一个电路图，有板子最好！“
再谢一声！我想同晶体管，集成前放作一比较。
现有的集成：5532缓冲+5532十倍。绅士金嗓子的甲类前放。

电子管不太懂，麻烦来几个图，先谢拉！

6j4两级放大推6p3p胆稳压。

6n3单级放大直藕6n4并联跟随器，输出用油浸电容。

我会建议用6N3，一级共阴放大加一级阴极输出。
