我的1543纪念板快完工了!
还差一些元件和变压器,其余的都焊上去了。
这个CS8412也焊上了,但愿别出问题。
8V时烫极了!!!不能不加
Re
散热?1543工作时很烫的吗?呵呵
xmlhifi兄的TDA1543安装方法和我一样,也不用座的,但我担心散热板会烤那四个退耦电容,现在心里总有点不舒服又一高手呀!

哈哈 楼主赶紧上来说说听感啊,期待ing。。。。。。。。我就知道楼主是猛人来的。
厉害TDA1543直接焊上的,没用IC插座。

收藏一个.我试验新版1541也是这样焊退耦的
实在是高!

退耦用0.1uF的MLCC
我的退耦电容在背面

有同感
以下是引用seabreeze在2005-8-28 17:25:00的发言:还是把四个退耦电解安到PCB背面比较好
PHILIPS的电容100uF16V
1543上那几个小油桶是什么电容
楼上的书记好眼力啊!
的却装反了。老大好象1543的硅桥接反咯?
不知道我有没眼花呢?>
