大家可以借鉴一下,呵呵...我也正准备弄1543...

按70楼万健兄所言调整即可.

万健

改在600欧左右，电压调到4V，

mcmlhz

你用了四块TDA1543并联后，输出的那两个1K的电阻有没有调整？还有需不需要调整TDA1543旁边的那个多圈电位器？

万健

我买了10块1543，选了有5片6。8脚输出电压相近

老明兄:
      我是把4个集成块重迭脚子对起来焊上后就插进原座里面去试的.太烫了.还是要分开才好.现在找了个长条形双面铜印板用刀刻装上4个座子,在第一个集成块下面装8个插针插进原座子内就OK了.只是要在原机座子上再插进一个座子升高它.不然会被8412挡住,插不进去.

老明兄:
      我末采用配对.因为只从钳版处搞了4块来.配对法好象站上有个帖子讲同样供电下测6脚和8脚电压(不调7脚电阻).区别其同样状态下电压.
      不配对将4只并联听起来效果都很好.而且TDA1543很经得起整.昨天我插反了一只.一摸4个集成块插反的那只发高烧.断电后插好仍然正常使用.但还是后怕.主要是我这里买不到.

用了不到50小时电池就无电了,所以改用变压器,在佛山筷子路买了一只思碧,24000U/50V要35元,好象贵了些,不知各位DX在广州买多少钱?我建议钳版开一个专栏让大家了解下各地元件的最低价格,毕竟大家都不是有钱人,有了参考价就算不可以砍倒JS们也不用大出血啦,我想这应该会受大家欢迎吧?

我那个飞线是接地,本来有分数码地和模拟地,理论上接不同的地方会有些差别,但这个DD是听不出的(我就听不出),由于我只用一只电池供电,又懒,所以就随便找了一个地接呀.我都没什么时间搞,所以只装了一片1543,你肯定比我高手啦,你的4片是如何布线的?贴图让我学习一下吧?

好老明兄:您好!
       你在板上集成块23脚飞了一根线去13脚是将23脚接地吧.我是把23与21在板子下面连通.好看些.不知效果上有无差别.
       另外1543用一片效果实在不如何.装上3至4片后效果绝对大不一样.只是集成块会很热.

如果说过气的话那胆机不是更过气么?大部分指标都落后于石机,但偏偏就有很多人喜欢,就是因为它有音乐味嘛.1543也有点音乐味,就是其它方面差些,但它可以并联呀,我准备搞128只并联,定制一只纯银漆包线绕的HLM(好老明牌)顶级牛,100A整流桥,100万思碧滤波电容,输出用MIT电容,当然线路改了很多,所以用铁弗龙(聚四氟乙烯)万能板,连线用纯银线,机箱用5CM纯铜板,最后用一百多公斤的大理石压顶,初步目标是超越Mark Levinson NO33......
[em11][em11][em11]开个玩笑,希望哈哈兄不要见怪呀,其实我搞这个1543有两个原因:
1.好几年没拿过铬铁了，所以才找个简单的DD来练习下。
2.从未试过网上购物,所以才找个便宜货来试下,虽然这次买回来的晶振似乎有点问题,但总的来说钳版还是一个信得过的朋友.
希望各位DX对我多多指导,少少也无拘
