没钱！只有自己做个1541

所有作品都是刀刻的(卖板的除外).连音箱的喇叭沉孔都的用割纸刀割出来的.我现在的正职一天用几小时刀却只能割个电源板.

现在让我用刀的话，估计第一个划开的是我的手指头。。同问；SAA7220哪里搞到的？？？？上个输出部分的线路学习一下。

我有台有图无声的VCD（人家送修不要了），想改成CD玩玩，错过了1543的团购，才自己做了个DAC加上，电源也从新做了（原来的看到就想吐）还好一次成功出声。现在1541的团购没米也放弃了，只好自己做了，HIFI方面本人不太烧，就是喜欢。虽然搞电子10多年。今年到这里才算入行了，在这里学到很多东西，1543也算是我的处女之作了，出声时就如回到10年前做实验成功的感觉，现在没那时的冲劲了。

做好了PCB，看来看去越来越不顺眼，加上也没做好（大家也看到了，有些走线断了，地线也不合理），二月做好的板现在还没完成，只好重做了。要在这里吸收多点再设计过SCH和PCB，尽量做个好点的（1543不满意）。还望DX指点指点！

不错呀！不过不用那么多走线的，脚与脚之间的走线越短越好。

谢谢小钳子的奖励，迟些我会把电路图和制作心得发上来的。[em08]

多谢指点，走线是长了点，我也正在尽量把连线搞到最短，就是不能兼顾。你的原理图可以发我参考参考吗？

我的原理图是自己画在纸上的，迟些才行。
