请看这个电路怎么样?
805工作就按这个电路,813我想省去推动级直接从第一级的屏极输入,这样切换时就简单了.但不知推动电压是否够了?三极管接法,还有什么地方需要改动?请指点,谢谢.<img src="attachments/dvbbs/2005-6/20056519149388.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/2005-6/20056519149388.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
