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.作者: jpgalaxy 時間: 2007-7-12 00:30
why need pcb ? change clock not only replace "tcxo-230" is ok.作者: alfcat 時間: 2007-7-13 23:19
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).作者: modi 時間: 2007-7-14 22:33
呢隻clock麻麻地,不過以新手去製作已算很不錯了,努力吧! 作者: alfcat 時間: 2007-7-15 09:54
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 ....作者: DUALXEON 時間: 2007-7-16 04:03

Where I can bought plastic mounts
Thanks作者: alfcat 時間: 2007-7-16 12:06
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.作者: DUALXEON 時間: 2007-7-16 12:48

Thanks for you help.How is clock sound.作者: alfcat 時間: 2007-7-17 07:02
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 ....作者: alfcat 時間: 2007-7-18 00:46
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.作者: viewer 時間: 2007-7-18 14:45
Hi alfcat,
I enclosed the photo link for you easy reference :
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! :作者: alfcat 時間: 2007-7-18 16:03
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)作者: alfcat 時間: 2007-7-18 16:35
Viewer 兄,
Please refer to the attached photos.
Please help ... :? Thank you作者: viewer 時間: 2007-7-18 18:37
hi alfcat,
the two gery colour wires are +-9v try measure it again.
thanks.作者: viewer 時間: 2007-7-18 18:40
hi alfcat,
one touch one of gery colour wire and other touch the RCA surface metal.
to measure.
thanks.作者: alfcat 時間: 2007-7-18 18:59
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?作者: alfcat 時間: 2007-7-19 20:24
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.作者: viewer 時間: 2007-7-19 23:58
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作者: alfcat 時間: 2007-7-20 00:09
Viewer 兄,
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. :作者: DUALXEON 時間: 2007-7-20 03:31

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.作者: viewer 時間: 2007-7-23 10:01
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.

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.作者: DUALXEON 時間: 2007-7-25 00:04

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! 作者: alfcat 時間: 2007-7-25 21:23
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 ...作者: DUALXEON 時間: 2007-7-26 01:51
