Pre351真是相當有料

[Coffin]

跟macosx大大買了兩張Pre351的板子，剛好可以裝在殺肉廠機的殼子裡。

整個機箱內觀，燈絲跟高壓用原來廠機的


主放大板，輸出電容用UCC SPP 6.8uF，底下偷並一顆蘇聯teflon 0.1uF；電源反交連電容也是UCC fastpower 22uF // 0.22uF SPP


屏極跟陰極電阻用22K的2W金屬膜，秋葉原製



輸入電阻是AB碳精，陰極電阻是秋葉原0.5W金屬膜


輸出是AB電阻，後面紅紅的是降壓電阻，中國的大紅炮


管子與電路


英國軍規CV2493


加上前級的好處當然是推動力變好，場面變大，低頻形體更佳；當然透明度略降，那是無可奈何之事∼∼

要不要換根管子試試看，貼個國外網站有人對這支管子的評論供參考

Mullard CV2493 – made in Great Britain with a dimpled solid disc getter like the Amperex Orange Label ECC88. Doesn’t sound the same. I have only listened to about 6 of these, so maybe I got a bad batch. All they seem to do is midrange and it does it very well. If for some reason you want less frequency extension, then this is the tube for you
