LM4780的一些资料，希望对大家有帮助

无线电与电视 04年1期的文章，写得挺好，看到坛子里要运做4780了，希望能有所帮助。
手里没有扫描仪，就用数码相机拍，还用上了三角架，可效果还是不如人意，论坛又有200K的限制，再一缩图就更差了：）大家勉强着看吧，点击图片放大看，是1200*1024的。

也不能怪我嘛，做LM4780时候是2003年7月，那时候咱们论坛还没有诞生呢～

时间太久了，其间重装了N次机器，重要文件丢失了很多……

稳压PCB的某处，有一个比较低级的错误；
好在无伤大雅，可以正常工作，呵呵～

用了三角架就是不一样，效果比平时手拍的好很多：）
钳版现在论坛空间还紧张吗？现在发图发多了觉得有点不好意思啦：）
