呵呵,好像我除法有问题??
昨晚上装好,一切就续,量量电压,高压310V~,7.4V~6.1V~,晕,市电238V,找来一乱调压器,调到217V,然后通电,灯丝全亮,怎不响???量电压,对呀,整流后330V。折腾了老大半天,还是不响,于是拆了电咸的线,一头有电压,一头没有,量电感,KAO,居然不通,该死的邮局!!!晕,死!!拆掉电感,用一300R线绕电阻代替,接光驱模拟输出,声音好闷呀!又晕,接上坛子的1543,然后,换了一只OTK的6N8P,开声,清亮多了(先上的是老南京的6N8,觉得低音足,力度够!推一小不知版的全频,听李烁的相见欢,觉得声音很保满,现在就是低频太重,高频暗了,好像有一点在箱子里发声的感觉(箱子也不行),我喜欢亮亮的,清清秀秀的那种声音!再加上有力度低音,听加州旅馆觉得力度不错。现在的电压是,6P3P阳极没测,但是供电电压是310V,阴极电阻390欧,电压19V,帘栅电压245V,6N8的和没量,6N8阳极47K,阴极2K!!请J版指导一下,另,用300R线绕电阻代用电感后 ,有很闷的哼声,不像是干挠引起的,我估计是电源滤波不好造成的,因为电容一共是47+47+22UF,帘栅极用了10UF的无极,阴极没好电容,用了普通的电解!
