Don't. Please make sure your circuit connection first.
If possible, please post your CDP photo at here.

DUALXEON,
Details have been sent to you, let me know if you need any further information作者: admin 時間: 2006-4-11 17:14
DUALXEON,
You may post your finished PCB online for our review before actual connection.作者: DUALXEON 時間: 2006-4-12 05:34
I still not yet to rec'd any info about
1)電源瀘波
欠電阻.要買幾多數席.幾大V數,焊接時那一個零件要分十∕一.怎樣分.
How can I post finished PCB online for your review before actual connection.
Can I got that info for my first step to modify my CD Player.

DUALXEON
Resistor 1*10Mohm, 2W (You may buy a few more for safe)
For +/- you need to make sure the choke connect with the same orientation as in the circuit diagram

You can take the photo of the finished PCB (front and back) for our review first before connect to 220V and CD player作者: DUALXEON 時間: 2006-4-12 17:43
Thanks
can I to know is it filter will work 100V to 220V作者: DUALXEON 時間: 2006-4-13 00:30
it is correct, include Resistor????
I haven't any idea which is input/output point,
compare to other class CD work shop, my filter still miss a part????
here is my filter作者: DUALXEON 時間: 2006-4-13 00:34

May I to know anyone finish this work.作者: kk_ho 時間: 2006-4-13 00:47
Dualxeon,
Please tell me about your value of the resistor.
Should be 10M 1W.
NOT 10 ohm!!!!!

Thanks for you so much
Tomorrow will be change 10M 1W.
Any part mistake????作者: DUALXEON 時間: 2006-4-13 09:09
finish work for Green light作者: admin 時間: 2006-4-13 12:03
DUALXEON,

DUALXEON,
Please remove the extra choke from the left hand side作者: louisla 時間: 2006-4-14 23:33
Hi KK,
我的是74HCU04AP, 請問是否合用? 可以怎樣接法呢? tHANKS
Louis作者: kk_ho 時間: 2006-4-15 02:38
Louis,
Your 74HC04 is not using in the Digital out.
This 74HC04 is use as oscillator work together with the Crystal
First, I assume that logic gate is for clock oscillator.
From the point of view of electronic circuit theory, the crystal itself cannot oscillate, it need something to make it oscillate, that IC form a simple loop back oscillation for the crystal.
If you parallel it, it can improve the jitter a little bit.
