<P>也可以用，12AX7的6.3V供电方法</P>
<P>但是灯丝要直流供电为好</P>

ruanhfgd 发表于 2006-5-2 08:07

<P>谢J版提醒，可以先用6.3V供X7的灯丝。</P>


aeon 发表于 2006-5-10 12:55

我以前搞过用12AX7做的二放.只要是交流声.用交流的怎么搞都会有那么一点的交流声.最后用317做一个稳压就没问题了...

<p>各位老大,</p><p>小弟菜鸟, 可否贴一个 13.5V做直流稳压12.6V</p><p>的线路图作参考.谢谢</p>

<p>最简单的就是使用一个LM317的可调电源!<br/></p><p>www.national.com/ds/LM/LM317.pdf<br/></p>

接到灯丝供电就可以了，注意正负要一致

<p>HJ-1直接当耳放效果如何？谁有试过？</p>

aeon 发表于 2006-11-27 09:32

不嫩直接做耳放，输出阻抗跟驱动电流都不能达到要求，如果把第二级跟阴极输出级改用6922等低阻管还可以勉强驱动高阻的耳机，但这只是兼容性的做法，耳放还是单独设计一个比较理想。。这个就当前级就可以了。
