可以發聲,但離好聽有相當的差距,原本RCA頭已經爛到不能再爛,連輸入都有略有底躁 拆下試著磨損出現黑色的鐵還是鉛的顏色出來,重做還是比較費工拉。 推 system1357 : 傳說中的只要輸出變壓器跟管子活著就有希望嗎XD 03/25 00:14 手工搭棚機只要管子跟變壓器還活著就OK,剩下去買替換材料就好。 ※ 編輯: f8y387512 (114
Can anyone shed some light on what they are exactly? Thanks in advance! vinylkid58 IP卡 狗仔卡
手中有几只FU32,广泛收集相关资料,对其在音响领域的应用甚是向往,很早就想DIY台机子,早年购买了宝而真的10K-8K:8Ω的推挽输出,刘哥又在网上给淘到了难觅的FU32屏帽,终于在春节前决定开工,于是开始动手。

1,fu32负压从-23v调整为-20v,,电流43ma; 2,重新调整了前级管的平衡电位器,使两个170的s极电位差为0; 3,重新调整负反馈,从5

Default Beijing FU32 vacuum tube, can be upgraded to GU-32/832; Default NE5532 op amp, can be upgraded to OPA2604, JRC4558, OPA2132, OP275 and so on for enjoying different tones
Finally, I added grid stopper resistors at the FU32 grid inputs
送料は日本全国1500円なので振り込み金額は2万1900円だった。
The last issue that needed to be fixed on my board is the B+ value: after the modifications it climbs to 265V, 15V more than the 250V max G2 value for 832A / FU32

原图网上自己找:6J1+FU32,这图是自己改成桥式整流,不用稳压管了。

#21 I see two issues: FU32 G2 has a datasheet limit of 250V, but on the schematic (post #20) the value is 294V; maximum G2 value for 6J1P is between 155V and 160V, on this schematic we have 176V
