求个FD422单端的图,简单音好!谢谢!

但是调试不好很难听

究竟SRPP的声音怎么样啊?

我一直怕SRPP前级 的音色会不会象石机,而没什么胆味啊?

具体说下共阴跟SRPP的音色具体区别好吗?


哈哈,主要是银弹不丰,只好 兵马未到,粮草先行了.

班长,图上怎么没有音量电位器啊,是不是纯功放?  要前级才能推啊?

6N1这样前级的推动力够吗（内阻有11K之多）？还有SRPP电路难调，而且声音象石机，我手中只用数字表，能否弄个好声的单端前级图给我啊！谢了！我第1次做胆机！
2mm不锈钢的外壳。面壳2mm的黄铜，底座1mm紫铜,长宽高是420x260x150,双单电源,
前级与后级分开供电(因为和后级供电要加一几十K电阻,其动态变小),前级电子管整流,后级晶体管整流,电源变压器和输出牛去广州买二手拆机品,请各位多指教,谢谢!

单端输出牛咋办？？那有买啊！米不多哦！

个人认为用一级五极管电压放大,推动足、胆味浓,你可试一试.

还有,前级电压从B+电压电阻分压得到,动态会不会减少啊?
我看见有文章说电压直入阳级,那屏流怎么调啊???
谢谢老兄!!

zhainm

担心的话就搞个简单的前级电源稳压。

zhainm

我也没做过这胆。
奇怪见到的多是SRPP前级电路，手里只有这一张二级共阴直耦屏出的，你参考一下吧。
另FD422是直热胆，噪声处理上要小心。
