剛完工的SP-10前級

今天剛完工 的發燒版SP-10
RUN-IN了一整天，聲音十分討好，人聲一流，低頻很爽，下潜很深！
小弟用GEC 6X4，第一級放大用一對Amperex E188CC，輸出級用一對Telefuken 6DJ8，全機用RMG，電容用M-Cap Silver/Gold。
先看看圖片吧！

kenneth兄你好,

我是DIY的新新手, 也參加了SP10 DIY計劃。
想參考一下閣下各個 組件和佈線的機內分佈。

另外, CASE可到哪裡找到呢? 謝謝您!

Case是台灣朋友幫小弟找的，好像沒貨了，連運費大概$1100
你們有沒有要升級包呢？
升級後音色十級跳

遲些小弟會將此機帶到HiFiFever供大家試聽

la1209 hing,

I'm interested, how much??

$7000

各位,

SP10 KIT 的TRANSFORMER 的  POWER INPUT 應如何接駁?

謝謝

kenneth 兄，高手即是高手！

剛成功通電了 ;)

我也開了聲！

感覺如何？

What is the unit on top? Looks very nice!

Cheng sir! Nice to meet you here!
The unit on top is DAC, from Novas Kao, called THE DAC1794!
Superb sound!!

請問preamp delay output 有甚麼用? 是不是必需的?

Dear la1209

你是否講市電入的位置呢？
如果是，很簡單的，火線L入電源座後經保險絲再去開關，
然後去火牛的IN，另中線N可以直接去火牛的另一IN就可了。

[quote:ea4560e02f="hmy"]請問preamp delay output 有甚麼用? 是不是必需的?[/quote]

在我而然是沒有必要的，因為開了CD機，再開前級，然後開後級，
如果前級的delay時間後，繼電器開了，那麼後級出喇叭便會有pop一聲了，
所以還是不裝好，要裝也是裝在後級吧！

謝謝您 MODI 兄!

一般來說，剛開機的膽前級，由於真空管還未算穩定，會有少量直流輸出，若開前級後立刻開後級，如後級沒有喇叭保護線路的話，喇叭便會傳出POP聲！可大可小！
小弟前級也沒有裝Delay，只要開前級待機十數秒再開後便可！
小弟裝的SP-10輸出約在1mV內，很理想了！

DAC是自巳DIY的，是用兩顆PCM1794做D/A的，小弟這台造價大概$9500左右！詳情可e-mail小弟查詢

La1209

Found your DAC on the web! Very nice.


Very nice. You have some many preamp now!!!

依部DAC可以話係DIY DAC的代表作其中之一！
動態強，低頻結實有力，分析力一流！
如喜歡以上特點的話，可以話係不二之選！

請問各位仁兄, 個volume掣應該點駁法?
另外可唔可以用sp10直駁喇叭?如果可以, 應該點駁?

RCA輸入接Volume IN，Volume OUT接PCB IN

多謝晒!

終於完成了! 開初唔識駁volume掣, 一擰volume後級即刻出煙, 嚇死!
好彩William嘅線路圖及時email泥, 我從新接駁, 終於成功開聲喇!
不過我有一個問題想問, 因為我用咗三部cdp做訊源:

1. Sony dvp ns700p ---- 背景有勁大吱吱聲
2. 大陸雞牌dvd機 ---- 背景亦有吱吱聲, 不過冇sony 咁大
3. Sony 十幾年前嘅Discman ---- 背景超靜

點解會咁?
唔通舊科技好過新科技!?

Hi hmy,

你可能在接地上出問題, 請確定沒有Ground loop.

點樣check ground loop?

唔知點解改極都有吱吱聲? 請問我嘅駁法有冇問題?

thanks KK and william, the course is very interesting & i've learn a lot.
