求助各路高手！！行行好了！

小玄

我想动手烧一下，搞一台10W左右单端，帮忙介绍个好电路吧！
     大家帮帮忙吧，我还是新手，刚刚到这，在此向各位高手们，大师们致谢！！！

小玄

好吗

小玄

6P6P和6P14两者区别何在???那种合适DIY

Julien

单端要是功率小点就好做多了

如果水平还只是在找电路图片盲目的胡装，还不是买成品或套建来的实在，建议先学学理论，之后根据自己系统来调画电路图。

10W若用MOSFET管子可选择的范围很大。[em11]

第二个图里面原来的电压放大管应该是12AX7

这两个EL34怎么样,特别是第一个,请教一下,

第二个贵阳文兄做过说可以的.还可以.

这个东西我已经完工了,用的是两支管.推力够大了,不过后来变压器打火,维修中.

就这样还能得输出15W？

另外也不推荐FU50，线性不好，内阻较高，并且是不允许帘栅极电压超过250V应用，否则帘栅严重超耗

可以到WWW.hbsdiy.com去看看我做的單推和推挽機.<img src="attachments/dvbbs/2005-9/2005922105330578.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-9/2005922105330578.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

功率很小

小玄

你还没见过那图呢?[em05]

Julien

小玄

12AT7推动，3个6P14并联输出那张

Julien

大师恐怕是 李X志 类型的了

小玄

我有胡志明那张15W6P14单端，想搞它，现正找牛，等我有料给你们看了，才看菜下厨好了。

狂之又狂

555。。。。。。初学还是等胆后级套件吧

Julien

狂之又狂

以下是引用Julien在2005-9-20 10:38:00的发言：
初学还作那么大功率的单端。。。10W是很大功率了

10W已是很大功率了,811能上10W吗
.....。。。俺不是高手
