交流输出电压２３０伏，请问８脚输出电压只有２７０，是否正常？？？

你先量量两管各极工作电压正常否?你说的啵啵声我想第一是电源内阻太大产生的阻塞,二是低频产生了振荡,你查查先,我也是新手,不一定正确

为何我的前级发出啵啵地响声？请问问题出在那？电源牛没零线只能用半波整流<img src="attachments/dvbbs/2005-5/2005562271314.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/2005-5/2005562271314.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
