再接再厉,再造牛机,空载50MA,无需散热片带200W灯泡,有图

昨天晚上用万用板搭的前级,变压器是以前绕的,初级0.55*12根,不知道是5*5还是6*6绕了很久了记不清了,次级绕了4层,EC42的骨架大概有180T吧.两对75N75,电动车控制器里拆的.

(发这个帖子不是要炫耀,我之前做了一块板子,相信很多人都看到了,多方求助才把它弄好,解决了空载电流大以及管子发热的问题,说句实在话,我搭这块板子的时候也就是想搭来玩玩,没想到用万用板搭的这个玩意竟是我做得最成功效果最满意的一个前级,其他具体参数就不一一说明了,都是按网上的那些图做的,很简单,没保护,也没加什么图腾.希望还没成功的机友不要泄气,坚持就一定会成功.
