EE55求助

我今天在深圳龙岗赛格电子买了个EE55磁芯,厚2公分.
我想做个JJ800W的,不知道能不能做到800W,我以前做过几台JJ,都是用电视机高频头磁芯做的,用这磁芯(E字型)还是第一次,初次级应该用多大的线?请各位赐教.500) {this.resized=true; this.width=500; this.alt='这是一张缩略图，点击可放大。\n按住CTRL，滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/80/3201291249555095.jpg?x-oss-process=image/watermark,g_center,image_YXJ0aWNsZS9wdWJsaWMvd2F0ZXJtYXJrLnBuZz94LW9zcy1wcm9jZXNzPWltYWdlL3Jlc2l6ZSxQXzQwCg,t_20');}" onmousewheel="return imgzoom(this);">
