金工.元件焊接工艺靓.外观有气势.强.佩服耐力！同花多少钱可做一对后级？
xiao12au7 - 2007/2/21 18:08:00
本后级使用300B牛推845单端,高压1000V电流68MA.单边重量大于150KG.次高压370V,300B电流45MA[upload=jpg]Upload/2007221183295039.jpg[/upload][upload=jpg]Upload/20072211835697952.jpg[/upload][upload=jpg]Upload/20072211843060175.jpg[/upload]
图片完.本套后级还差前面板和装饰木面板.春节后做出装上即可.机器声地厚实低音厚度好过300B单端很多.有300B的中高音区表现.好牛的结果.

考慮到高壓絕緣性,建議管座換老美製的,現代的品質不行,

这个胆机我好像在别的地方见过，一模一样，两只845给一只845整流。
光金属外壳材料费就不得了，一对后级大概售价多少呢？ |
此款机器只在北京有两套,一套就是现在这个,还没最后完工.
机器每边是用两个845做全波整流.输出1000V给845做单端.次高压用5U4G整流输出370V给300B做单端推动.前端用6SN7一级推300B.
电路结构:6SN7---300B--LL1677/80MA--845--LL1688/70MA
此款设计可能不再出品．成本太高．现在这套做绝版收藏．如有定制例外．
