[quote:69781899b0="dynamicdog"]DY2000 噪音會唔會太大?
有無試過用 2 粒OPA627AM? 線條應該會幾靚[/quote]



手上己經有2粒鐵殼627Am.不過部CD己經比左我朋友玩.短期內都唔會取回.所以唔知道>是否線條應該會幾靚.

經過個多月.開始MOd

致sunnyhk兄


你可否比你電話我交留下.你每天一個Emai1挑誘我.


【說我的CD機剛摩完，一開聲嚇了我一跳，聲音亮麗，力度十足．我從未在我的音響組合】


點先 :?:

換膽、換0p AMP 換Fsue

正式開始Mod
第一步改Resistors及整流.悍工不要講.我自己知道.朋友悍.我自己一粒都無悍過.自己悍肯定差很多,無辨法人又老眼又花手又震.



有D整流改左才知好熱.所以要好像把扇分開.

又來一幅整流.

可故有D改、有D無改 、柯打時數少左.


有無人可以講比我知在邊到買到呀.

william ,K K Sir 可否補購.我欠5粒BYV27-600

KK Sir ClocK 身價唔嘢少.

個C|ock從上面看得三件零件,反轉後面看.

[quote:4f883add85="kk_ho"]DualXeon,

I will send the diode to William office at this week.

Please pick it up at next week.

Could you share your result of the modification.

KK.HO[/quote]


pick it up at next week. it is free \/

最後我會有個總結.

換Clock後聴了2日.現在可以換JENSEN CAPACITORS


空中之城全部飛起.心急聽下先.

停手計數,部CD機三千幾(改機用).到現在換了

2枝 金腳 AMPEREX 6922膽                         @$800x2
2 粒 OPA627AM鐵殼                                    @$120x2
2枝 JENSEN CAPACITORS                   @$400x2
Fsue                                                $25
Resistors                                          
整流                                                                Resistors十整流 大約400
Clock                                                $1200
HiFiFever學費                                                 $380

己有料遲D改.
內部電源絲Belden 20A $50、接絲Taralabs TARA LABS 'Rectangular Solid Core' RSC $500、電源罩$30.等等.

自己手慢改東西又多.在HiFiFever 2個晚上根本沒法完成.要在家改所付出工具錢.大約$1000.

己經貴過部機價 .將手上零件換上應停一停.

Willam BBCode 太簡單唔多夠用,HTML 好D.

[quote:3be9a77746="dynamicdog"]DUALXEON 師兄, 你好勁! :shock:[/quote]



邊到呀 :?:

今天行去旺角麥氏,銀包又輕$400

本來部CD用MultiCap RTX 頂級,心想反正都是換JENSEN.

今天晚又改了小小.安放好2枝Jensen及Clock.



煲一個星期.

[quote:b4bbe522a1="TWM"]Your clock seems to be quite far away. Any concern on interference?[/quote]



TWM
Thanks for comment, any good suggestion
You advise can improve my modify skill

[quote:c836cee46a="kk_ho"]DualXeon,

Your clock placement is correct. Please don't move it.

KK.Ho[/quote]


  
What about JENSEN CAPACITORS placement any comment. I have got some more idea is replace 2 pcs R Core Transformer one for dagital an other one for Analog and that design newly layout move Transformer place on middle.
Can I pick up 5pcs BYV27-600 整流 on Monday.

今天在家發現一對靚線.放落CD機聽.一聽不得了.點解.
大鑊到現在至發現換線比起摩機改進大好多.像2604 0P AMP 換 627.
晚上聽了一晚.再沒有Compare改前點,改後點,只是溶入音樂.也是我最想要的事.

【我不是說改機無用.只是說換靚線改進好大】


看相

經過昨天大改進,今天拿走跟機膽,用反D平時用開膽開聲.

前 > 吹喇叭十德
後 > 貓

又有改進.
一個字【正】.

[quote:0f11a853da="wieder_singel"]Hello...
How is the sound of the CD-66 without the modifications ?? I would like to buy the CD Player...
Very Thanks from Germany..
Dennie  :wink:[/quote]


Acceptable

I recommend change OP AMP to 627 Bp and tube.My purchase thru HIFIFever Willam Sir with discount.

[quote:4cf7c6f19e="wieder_singel"]Hello Dualxeon
Thanks for your fast answer.

Greetings Dennie  [/quote]



You Welcome

今天收到BL0CK GATE,明天又可以繼續改.

Install Black gate cap and OS con Cap by someone help already but CD player runin on my friend home.update photo will post late.

[quote:1fa524d390="Newton"]我是路過的...
你們有比較過SPARK CAYIN CDT15 ?? 有什麼分別?
請賜教[/quote]


SPARK CAYIN CDT15 沒有比較過,和17A國內版比較過.我當然說摩改後大獲全勝.

[quote:b31b3ae788="dynamicdog"]期待你o既新相[/quote]



我都知你們期待,我比你們還心急,但是我又控掣不來,在HiFiFever上堂自己又手慢改嘢又多,要拿回家繼續,改到才發現有問題,包括(手藝、知識)便停手.
手藝請鎗手.
知識問人.

到現時想加一隻獨立牛及隱壓給CD CLock.ca|| KK Sir幫忙問個CLock info.我都在等.

經過多天在朋友家Run in.我朋友己經換/升級CD機.點解.

聰明的你們,一定估到原因. :


明天拿去第二朋友家Run in.

最新消息換0p Amp最好加個專用

是,我都見個部新機.Chris話新機好好多,




[quote:0cd6002ca4="dynamicdog"]

Chris用緊呢支野? 尋日上去見無咁細支,好似成部AMP咁大,可能火力已經升級左, 睇下佢幾時拎支火箭炮出黎玩[/quote]

ozrayyau兄
玩HiFi姊唔冼想死呀!!!!!
你有無用其他機試過.確定問題在CD機.
你有無多手摩過部機.



[quote:771d18b2ee="ozrayyau"]我都買咗呢架機,我果架喺relay開咗(的一聲之後)仲未有音樂果幾秒/又或者音樂好細聲時,就有wee wee聲,音量喺10点左右,唔知各用家係点呢?好想死呀 [/quote]

Why Sir

你部新機山靈是 OPA627 #-o



[quote:0d7ec2fba9="why"]KK Sir, Dualxeon hing:
OPA2604 is two channel OPA,but why my CDP has two OPA2604? How many OPA627 should I buy to replace them/[/quote]

Why Sir

KK Sir already to said

Opamp inside the CDP for the following function

LPF (Low pass filter)
I/V conversion (Some DAC is current out)
Mixing (some DAC is differential out, use it to convert to single)
Buffer
DC Servo (SCD-1, CDP-XA series)


I will change audio tube first.
