谢谢大家,昨天做了个LM1876,出声了,感觉可以,玩得有点上瘾了,休息天开始开干个马蒂斯,配IC功放,再次感谢各位

这个怎么样?我只希望替代运放驱动LM3886,放大倍数5倍左右就行

Julien兄功夫过人。这二个都不好，第一个好像推力不行，搭ZEN4时低频份量多就有阻塞感，有高招吗？

kim66

高见,佩服,能否告诉我用什么廉价的管子可以代替?

Julien

且线路增益大了些，对于10K内阻的6N3来说，20K屏极电阻小了些

kim66

谢谢,大家,给我的感觉第二个电路电压太低很容易失真,第一个电路末级动态范围小了

我也想知道第一款电路能达到什么程度，云外天上说的是很好，手上正好有2个6N3T，想做来玩!

这些搭了总不尽人意的，要不就试试马蹄，M7，C22等名线路比较有保证。
要不看看J版主的前级套件什么时候出，

这一款呢，雨果把6N6换成6N3应该没问题吧？
