新作的功放，，功率管真伪？

刘民

我新近买的管子砸开里面也是这样，管芯是比较小的，同样也是这样的外观。
这样便宜的管子造假也没什么利润吧！

老管和新管的差别吧

其实都是真的,
只是厂家为了减低成本,
改进的材料,
其实特性都是一样的,
你可以测试看看的.

TIP41、42是廉价管，不会有JS造假的。

很早之前，曾经在装机时无意中试过该管子的可靠性：用这种对管作功放的输出（因为便宜，又有一定的电流输出能力），但是是试机时，散热片用的很小，就像是中功管用的哪种吧。在装机时在散热片的局部表面无意中打了一层蜡，通电后声音正常，因为高兴而忘了测静态电流，回过头时闻有一陈浓浓的蜡味，用手一摸管子，瞬间烫起了一个泡（回想之前不小心手指碰到烙铁头也差不多这种效果），估计有200多度吧，心想坏了：这管子肯定烧了（因为像之前用别的管子还没有这样的温度就早坏了），把管子拆下测量下，哈~居然是好的，不得不对这管子另眼相看！所以说到这管子时印像特别深刻，可能是因烫了一下的缘故吧！性能参数不怎么样，但很便宜的管子！

谢谢！很详细，学习了！

老徐，TIP41 1块5很贵了

我买1块钱啊，我都整条包装拿的就是了

不是TIP41 TIP42 的问题,是你的线路太牛B,供电太高,放大倍数太高,不烧才怪.

hello ,friend of jiangsu_china,ga……ga……ga。I love you this simple circuit, sound good, is that choosing the right pipe, the sound is very interesting that, although I have the equipment, did not call me arrogant than in the forum few friends, but I always like to use the ear to take the delivery, so, listening to the comfortable, of course, comfortable personal point of view, the need to continue to invite fans to join listen to audio, to hear their views. In the end, all the equipment I stood rusty. This is just a simple circuit, is still the winter ridge characteristics, some people will believe I saw the nonsense: "Simple Line, ah, many under the bed." Characteristics of this circuit is that he is for linear circuits, it is a very good Class A and B, actually, you look PASS C12, know you this line and it has the same purpose, I'm not strong organizational skills language, abusive habits, but not write to write these statements came Sven, Of course, I hope you will plan out the whole PCB, at least, I used to do a piece of universal circuit board, around several predecessors have said sounds good, then a simple line, actually able to do voice Jihuan have caused, IF fine sweet, high-frequency clarity is not harsh, drawback is the sound major, but because of pipe problems, low frequency, or the need to explore how to adjust the intensity. You make a PCB program, so that jar with the real fans can feel as soon as possible.

SORRY,我还是用中文写出来吧，我非常喜欢你这款简洁的线路，声音不错，属于那种选择适当管子后，声音很吸引人的那种，虽然我拥有的仪器，并没比在论坛骂我狂傲的朋友们少，但是，我总喜欢用耳朵来收货，以至于，听该舒服了，当然个人观点舒服后，还要继续邀请音响爱好者来一同听听，听取意见。最终，我那些仪器都放着生锈了。别看这电路简单，实际上还是挺有特色的，有些人，会一看就信口胡说：“简单线路啊，床底下很多的。”这款线路的特色是，他是给线性线路，而且是个很不错的甲乙类，实际上，你看看PASS C12，就知道你这线路和它有异曲同工之妙了，我语言组织能力不强，骂人习惯，写这些斯文语句反而写不出来了，当然，我更希望您能整个PCB方案出来，至少，我也用万能线路板做了一块，身边几位前辈都表示声音不错，那么个简单的线路，竟然能做到声音急缓有致，中频细腻甜美，高频清晰不刺耳，缺点就是，声音大是大，可是因为管子的问题，低频力度如何调整还是需要探讨。您做个PCB方案，好让坛内的真正爱好者们能一起早日感受一下。
