改 CD33 的鐘 / Changing CD33's Clock
各位兄弟,忙裡偷閒來試吓改CD33個鐘.先看看買回來的套裝配件. 完成品.
一個唔認識電子的傻佬造出來的東西唔知有無說服力 ....
如有錯失,請各位大哥指正.

Wow, this is one PCB done by an Electronic Idiot / Dummy. Will I be able to convince you?
If you spot any error(s), please don't hesitate to inform me as I don't know any Electronics (I am serious). Many thanks. why need pcb ? change clock not only replace "tcxo-230" is ok. 今日又做到趴街, 結果又無得再續下文. 只有星期一再整埋落去.
Been working like a dog today. All modification came to a halt again. Will resume on Monday (have my fingers crossed). 呢隻clock麻麻地,不過以新手去製作已算很不錯了,努力吧! :D Modi 兄,
作為入門級人馬, 只有用這個做實驗品. 多謝你的 encouragement.
我暫時都係整魚缸叻過整 Hi Fi, 話晒做魚缸三十年, ha..ha..
不過我話俾老婆聽想再整番個魚缸, 佢問我係唔係想死 .... Kitty Sir
Where I can bought plastic mounts
Thanks DualXeon 兄,
Better call me "Fat Cat" or "Alfcat" .... Kitty is a bit "feminine". 話晒我都係 "佬" ....貓公一隻 .....唔想太乸 ... 請見諒.
For the plastic mounts, you can go to Golden (middle floor). Those shops selling IDE cables, etc. should have these plugs / mounts.
If they don't have it anymore, go to NEW Golden Computer Centre. There are some Second Hand shops there. They should have these mounts but of course "second hand" type.
I am also asking a company if they have this mount for you. Give them a day or two to reply (through email). Will post you another message later. cat sir
Thanks for you help.How is clock sound. 尋日做咗成朝, 食午飯時拉咗亞秋官陪我行旺角 .... 結果買了 Antique Sound Lab AV 25 Mono Block 後級, 用 EL34 或 6L6. 跟隨上 seminar, 食完晚飯去了同事家幫佢整電腦 .... 返到屋企成 11 點, 無力再玩 .... Totally exhausted. Sorry fellows, it is easier for me to type in English.
I finally set the clock PCB right today. After removing the old clock, I connect the Date Line just like Viewer did and got the power from the main PCB of the CD 33 at 9V.
However, when I power on, the machine gives "tic .. tic" sound and no reaction at all. I was so scarced that I turned it off immediately. I tried one more time and the result is the same.
Sorry fellows, without an expert by my side, I finally re-arrange thing back to its original shape. Luckily, my CD 33 still works. Thank God about that.
I think I won't touch the clock again until I have a chance to see KK Sir and ask his expert advice on this first. Hi alfcat,
I enclosed the photo link for you easy reference :
http://www.hififever.com/forum/download.php?id=5891
I think you connected the 100v line .so you measure high voltage.
the 9v is near to topside of the square area of the photo.
Thanks. Dear Viewer,
Yes, I used this one. There are 5 holes. Bottom ones says 100V (which I measured only +38V using my meter).
Second one is BLANK.
Third is +38V (measured with my meter) and the Fourth, Fifth are Ground.
Also, on my PCB where the original clock is, there are only 4 pins which form a SQURE. But the new clock is RECTANGULAR. How can I fit the new clock in the CD 33 PCB if I omit the "clock kit pcb"?
I will borrow a camera and take some photos. I sold my camera some months ago. The past photos were taken by my office camera.
Thanks for your help. I am so glad I see you here again!:lol: To DualXeon 兄,
我今天行過高登, 問 D friend 拿了一堆 Plastic Mounts. 你係唔係要? 我可以俾D你 (e.g. mail to you or pick up at MTR) Viewer 兄,
Please refer to the attached photos.
Please help ... :?Thank you hi alfcat,
the two gery colour wires are +-9v try measure it again.
thanks. hi alfcat,
one touch one of gery colour wire and other touch the RCA surface metal.
to measure.
thanks. Viewer 兄,
I tried BOTH Grey wire. I put the RED on the grey wire and the black on the metal body of the CD33 ... all readings give 3.4V only
Is there something wrong? Viewer 兄,
如果唔係這個位置取電, 可否在別處取?
又如何將兩個 3.4 Volt 加埋做 ~ 7Volt? PCB 兩條線, 咁條GND去邊呢?
請教路 ... Many thanks. HI ALFCAT,
何將兩個+- 3.4 Volt 加埋做+-7Volt 接去 PCB ,因為這個CLOCK 是用+-入電 ,條
GND就是PCB 正方形OUTUP 圓形是訊号OUTUP接去ORIGINAL CLOCK 位 OF PCB OF CD-33在圖中黃色格GND ,綠色格便是訊號OUTUP.(我也記不起黃色或綠色是OUTUP)
如果接錯不要緊祗要CHANGE 位)
你是否已CHECK THE READING OF 電阻 OF CLOCK'S PCB.

HOPE TO HELP YOU Viewer 兄,
換鐘終於完成了. 但因為已三更半夜, 未能將音量較至正常高度. 暫時不能說有幾好. 不過我感覺上唔係太大的差距, 可能因為我部機唔夠正.
I got the power from another source of the CD 33 PCB. As it is already very late, I will post the photos tomorrow afternoon after visiting my ex-teacher.
Anyway, many thanks for ALL the help you have offered and sorry for all those disturbing calls I made to you.
Thank God it is finally done.:lol: Cat Sir
恭喜,經過多次錯販是否好有成功感有無大叫一聲〝B|NG0〞.
可否Post張換C|ock後相上來看看.最好能看見你取電位及C|ock放置位,我比我學下嘢.
我己經買了膠坐.多謝. DualXeon 兄,
剛剛好拍完的相. 因為這部相機質素較差, 希望可以看得到吧.
To Viewer 兄,
雖然我無電子常識, 不過我估到點用個 meter, 所有電阻已度 OKAY. 多謝你提我! Cat Sir Morning
Thanks for you photohttp://forum.timway.com/f/images/smilies/verygood.gif. How is the sound after reclock.
你個C|ock放得太遠http://forum.timway.com/f/images/smilies/saujai.gif,應盡可能放近舊C|ock.條線去C|ock盡可能短及靚.另外C|ock取電位在數碼部份.
你部機摩前有無做boby check確定全頻0K才摩.簡單方法放隻20Hz - 20KHz訊號CD播放順便知道自己套HiFi有幾多斤両.
今日飲多左http://forum.timway.com/f/images/smilies/beer.gif,講得太多.下次隔離牛.http://forum.timway.com/f/images/smilies/shutup.gif
供參考.KK手工凈C|ock部份 DualXeon 兄,
架機未有得 Check Up 住, 因為 KK Sir 好唔得閒, 重等緊佢.
條 Signal 線是 Kit 跟來的, 我都好唔鍾意. 可以用什麼換了它?
好多謝你的提點, 過兩日我會再加修改. 老虎乸:evil: 明天返, 一定要係佢返之前整好其他嘢.:cry:
千祈唔好話講多咗嘢, 你咃做帥兄的唔出聱, 我哋今世都無嘢學得到 !
"重有C|ock取電位在數碼部份" --- 這個是否不恰當? Viewer 兄,
重係唔係好明點將兩個3.4 Volt "加埋" 做 ~ 7 Volt ... D線應該點 connect?
Very sorry. :lol: 好啦好啦, 老虎乸明天回來, 今天要將所有東西打回原型. CD 33 也完功了.
再將啲 Hi Fi 係咁兒放回原位 .... 大功告成 ...:lol: Cat sir
你間屋同音響http://forum.timway.com/f/images/smilies/loveeyes.gif

唔好笑私我啦 ... Post 相出來因為早前請教過我對 speaker 要唔要用釘 ... 有大哥叫我 post 個 setting 出來看一看先 ....
個 Clock 換完之後我聽過幾次 ... 但唔覺分別好大 ... 只是像CD 機個膽由 WE 396a 轉去 Bendix 396a 咁上吓 ... 我相信因為我部機主為 Budget Buy ... 所有東西加埋都唔 HK$10,000. 比起我同事 D 機最平的一件都差一段 ...:oops: hi alfcat,
would you mind to tell me where to buy the mono power amp and how much?
give more time to let the clock and cd-33 run in, it will be let you have a suprise.
Thanks for sharing. Hi alfcat,
good morning !!!!
I have read a review from the following web site for modification of you mono block power amp for you reference.

Thanks for sharing. Cat Sir
有無CD做Test.result 如何,希望你部機無蟲. Viewer 兄,
好多謝你的資料, 我會去買d caps 來試吓. 至於隻牛, 我部係 AV-25來的, 無須要改.:lol: DualXeon 兄,
小弟正四圍問人有什麼地方有試機 CD 賣. 如你有資料請賜教.:P cat sir
我幾天前emai|你經HiFiFever. 個 Clock 換完之後我聽過幾次 ... 但唔覺分別好大 ... 只是像CD 機個膽由 WE 396a 轉去 Bendix 396a 咁上吓 ... 我相信因為我部機主為 Budget Buy ... 所有東西加埋都唔 HK$10,000. 比起我同事 D 機最平的一件都差一段 ...
--> Depend on which CLOCK and Regulator board you are using.
And the skill to draw the VCC.
HiFiFever have 2 idential CDP, which is using for comparision.
Mod class coming soon.
Still busy at normal business work.
KK.Ho DualXeon 兄,
已覆了 email ... 真是對不起 Dear KK Sir,
My colleagues are busy doing the timetabling for this few days as well. Hope to have it finished by tomorrow.
I am having my first week of holiday, enjoying CD music and doing some shopping for myself.
Just wonder whether Hi Fi Fever can have a class for Electronics 白痴 like me. I really want to learn what are the uses of resistors, capacitors, relays, transistors, vacuum tubes and their classifications. Not to mention HOW to read circuit diagrams ...
Looks like I am greedy but I think Hi Fi Fever had a class like this last year. I "think" some parents may be interested in taking their kids with them for class like this.
We will wait for your reply on the CD checkup. Cat Sir

我換C|ock後感覺同你一樣真麻麻.問Stephen大哥拿條靚線玩好過效果明顯好多. DualXeon 兄,
唔知有什麼問題, 寫完俾你的 message 唔見咗 ....
Anyway, 希望今次 send 到你那裹 ....
我都有一個 friend 幾鍾意玩線 ... 但我就玩唔起啦 ... 千幾至幾千都有 ... :(
不過 D 聲係有分別 ... 得個 "恨" 字 ...
I think you have my number. You can call me anytime from 7am to 11pm. I won't be available this Fri, Sat & Sun. Many, many thanks! :D DualXeon 兄,
剛剛找來了一家之老虎乸來試一試聽唔聽到有分別 ... 佢好用心聽話有, 但唔大. Piano 清少少 ... Background 無咁多noise, 而空間感大了又是少少 ... Cat Sir
有人跟你一起聽歌及比意見還有早睡早起身體好.你真幸福. DualXeon 兄,
唔好攪錯呀, 隻老虎乸係 "請" 出來幫我聽五分鐘歌 .... 平時叫佢聽, 佢話這個唱得差, 那個唱得無感情 .... 乜 mood 都無哂 .... hi alfcat,
你說:
[剛剛找來了一家之老虎乸來試一試聽唔聽到有分別 ... 佢好用心聽話有, 但唔大. Piano 清少少 ... Background 無咁多noise, 而空間感大了又是少少 ...]
這就是換clock 的 result.
你太太的耳聽 better than you. ha ha !!!!!!!!!!!!!!!
恭喜你有位 hifi tester.!!!!!!!!!!!!!!!!!
Thanks. Viewer 兄,
我老虎乸是學琴的, 所以某 D 音節佢會清楚過我.
但我覺得最明顯的分別在換了對 Bendix 膽 ... 分別係人都聽得出 ... :lol:
