昨天装了一个3886功放

<p><font face="Verdana" color="9445650"><strong>sheldon：没问题！</strong></font></p><p><font face="Verdana" color="9445650"><strong>寻星向南：</strong><font color="-33554432">1342V</font><strong>唯一的可调电阻是调偏流！推荐正宗三肯对管C2922/A1216，或C3264/A1295，一对即可，勘称绝配；电压推荐直流45伏或交流32伏，末级电流调到300mA；传统的功放近年来都没有太大的改进，线路、元器件、工艺等似乎十年前就到头了！所以UPC1342H是绝对值得你去精心装调的！</strong></font></p>

涌泉的那个老袁好像后来在对面金粤开店，现在没做了。据说是做的胆解码器被原创公司看上了，聘去当工程师去了。

UPC1342V用场效应管输出电路要改动吗？

<p>喇叭保护收到！很不错！！！谢谢老兄了！</p>

寻星向南：要改动，但改动极小，G极电阻要增大，为100欧；双极性三级管的CE两脚要交叉！因为K1058的脚排列为GDS；周末去平乐古镇了！上张照片，劳逸结合！
