j版主你能给我一个ＦＤ４２２的图吗？

请ｊ版主你能给我一个ＦＤ４２２的图吗？最好是６Ｎ８或是６Ｎ３两级共阴推的！

Julien

V1的阴极电压上面写着3V了，屏压你用欧姆定律总能算的
V2的阴极电压105V也标注了啊

利用特性曲线很容易知道V2是320V左右

至于V1的取值有点高，帘栅压严格来说高了些，可以也使用320V
不过两级推动FD422完全是多余的

Ｊ版没标Ｖ１，Ｖ２的电压呀！<img src="attachments/dvbbs/2005-10/20051013214032518.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/2005-10/20051013214032518.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

音色什么好我不清楚，不过可以用五极管

菜鸟又不懂?不能怪偶等 , 还是要打你PP

你说FD422怎么推好 , 1级推的话用啥管音好?
