哈哈，钳版，我的1541也到了

不用接灯丝，5脚接正，2脚接负。
但你要并接在180V电压的电容上。太低了点不亮的。[em05]

这个稳压管只要接2个脚就可以了吗？灯丝什么的都不用吗？

好消息：
我说过了，我的高压绕组是双160V的，这时屏压有163V,阴压2.5V.
我在第一个1K电阻后并入一个WY--4P充气稳压管，这时屏压降到了130V,阴压2.04V.
但噪声小了许多，现在在12点时的噪音等同于未加WY--4P时的11点。
看来高压稳压还是有必要的。问题是我的机箱里已经很挤了，恐怕要另谋计策。
各位可一试

排除万难，不怕牺牲后。本人也开机了。声音正常。VOLUME打到11点噪声很小，打到12点有较大噪声[em10][em10][em10]
我的高压较高，有160V,按以往装机经验应问题不大。6n11我还用过250V呢，
