標題: 新手 DIY SP-10 前級疑問
第一次 DIY (用 PCB) , 有點不明白想請各位大大指教
幫忙~幫忙~

ops:

(1) PCB 用銅柱 (好似電腦) 固定係機箱 ? 還是有其他方法?

(2) Transformer D 線點"旱"係 PCB? 用"玉斬" / 其他方法?

(3) Tape / CD / Phono 個 switch 應該點整?

(4) VR 用 ALPS / 24 steps volume 怎樣接連 PCB?

(5) 若有大大可以影些機內裸照, 尤其是.. 全相, VR 接連PCB , 兩 PCB 接連部份, power switch 接連PCB 部份.. 就好了, 當指教一下小弟

感激不盡~~~

1) 用銅柱
2) 火牛線直接焊在 PCB上
3) 先做一組輸入, ok 後再加selector
4) RCA -> Volume -> PCB
5) http://www.hififever.com/forum/viewtopic.php?t=1037&highlight=sp10

good~

btw, C8, C9, C10

the capacitor given value are different from component list

component list = 0.01uF 1000v, but given = 0.1uF 400V (not solen)

any problem? or wrongly given?

我唸你話六隻腳開關，應該就咁駁！

作者: mbcy 時間: 2007-1-21 02:31
yes

your response is so fast
thanks
i have already finished the power PCB part

how to connect

hehe
sorry for my stupid questions....

作者: mbcy 時間: 2007-1-21 02:42
for the ALPS part

the red rectangle, what is the point for connecting?
thanks[/img]

只是為了不重疊的線給你看得清楚，才這樣走線。

good night

You should use the AC mill-meter to measure the S/N ratio via you trying difference location of GND point.

From your diagram, you connect L/R GND together and tighted to GND point.

POS : The noise will be lower as you tighted the GND at beginning stage

CON : Poorer channel seperation

你用高級電源插頭嗎?

換過帶保險絲連開關電源掣.開關要加退火電容.

還有新人千萬不要一個人在家的時間做.你明白那個嗎?

你一定是沒付學費. [-X

SP 10 在這裡經常有人說開大聲有燥音.

預祝你成功.

Thanks all brother

那麼上面那些圖是對的嗎?

(1) GND 是否= PCB GND接銅柱接機箱?
(2) 黃綠水線(牛) 不用接 IEC? 接 GND?
(3) 用 Fuse + IEC ?? = IEC 連　Fuse?

thanks
