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.

膽負責放大,咁OPA2604作用係乜?淨換opamp有改善嗎?作者: kk_ho 時間: 2006-7-10 12:47
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

How about the Opamp functions on Mhzs CD33作者: why 時間: 2006-7-11 12:35 標題: All OPA2604 can be replaced by OPA627 KK Sir,
MY Sony CD is also uses 2604 in analog out, Last time , you suggest me to replace by BB's opa2604. If 627 is better than 2604, can I replace it by 627?
Thanks作者: DUALXEON 時間: 2006-7-11 15:10
最新消息換0p Amp最好加個專用作者: kk_ho 時間: 2006-7-11 16:50 標題: Re: All OPA2604 can be replaced by OPA627 Dear Mr.Why,
OPA2604 --> Dual Channel Opamp
OPA627 --> Single channel Opamp
if using OPA627 for replacement, you need to add a 1-to-2 socket over the OPA2604 location.
Like Dualxeon provided pic.

Hi KK Sir,

How is you improvement after replace to Op amp 726. :?:作者: happy4 時間: 2006-7-12 08:12
Hi Dualxeon,
I miss too many adapter issue.
Reason:
Due to the lower layer soldering easy to break down the PCB use 1 additional adapter for protection. The converter single OPAMP to dual OPAMP is use for testing which combination suitabe for me, the last adapter is due to buy 2nd hand.
I brought the OPAMP in Kwun Tong & SSP.
Thanks for you advise.

Hi Dualxeon Hing,
After getting your valueable comment, I do the change on the unaccepted adapter.
Remark : due to my soldering skill not so well, the contact point on the PCB near break down when I fo the replacement, good luck for me it still work.
Beside the new adapter, all the Capd had change on the output board.
most are OS-CON, ELNA, & Black Gate.
Now waiting for 200 hrs run in.
Waiting for your comments on the your Super CD player
