各位兄弟早上好,因上周末忙,无来得及处理晶震的事情,在这里向大家说声对不起,明天开始继续。广西的朋友,你的晶震尚未发出,明天一起处理,

不客气 !我用的是 台湾 TXC 的16.9344 MHz 晶振 !
说起晶振, 就有好多商家制造“时间长数网 ...

猫版您好,这个是否你说的TXC晶振吗?

最近陆续有兄弟询问购买磨改63/67零件的事情,这次报名周期长点吧,截止日期为9月30号,国庆节后买零件;如有需要请PM。

猫版 这里有个这样的修改方案 请你看看!
Capacitor replacements with Sanyo Polymer OS-CON's for Digital. Stock Elna Cerafine for Audio are already in place so they weren't removed.
Changes done to the clock circuit are two Silver Mica capacitors mounted closest to NPC SM-5872 DAC underside of the PCB.
Also the Crystal outer metal case is grounded and a few other mods done to the DAC as well.
The AC inlet is filtered for RFI now using a choke the round white thing far upper left side inside view.
Added chokes to all voltage inputs to the DAC and OP-Amps for cleaner DC.
Removing the muting transistors and output capacitors help open up the sound a bit and you'll here more definition.
The DC blocking output capacitors were not necessary since there is very little DC voltage emitted from the two OP-Amp output pins no. 7 anyway.
There is one drawback to removing the muting transistors as you will hear a pop noise through your speakers when you turn it on,
So its best to have the volume down low or turn the CD player on first before turning on your amplifier or receiver.
HDAM circuit is bypassed so only the two L/R Burr Brown OPA-2604AP OP-Amps which are in sockets are then connected directly to RCA jacks.
The HDAM circuit hampered the sound quality so its not needed. Also by removing it from the voltage supplies reduces power consumption.
The two large 3300uF Nover filtering capacitor metal cases are dented but doesn't affect there operation or specific values.
This CDP was modified for Vacuum Tube outputs and was used more for testing purposes. Since then the tube circuits were removed and
OP-Amps are now being used. It does not have any issues it plays fine and sounds great.
The cabinet has Dynamat and rubber added to eliminate unwanted vibrations.

零件差不多到齐了,无奈看了两天贴子还是有点云里雾里的,不敢动手。请问猫版和大家以下零件的更换是否正确?我的机是CD63。
4.2200uf 50V电容器 2个, 更换C803、804
5.WIMA 10nf 63V 电容一个,更换CD04
6.WIMA MKP10 4.7uf 160V 电容2个 (已贴双面胶) 更换C657、655及C656、658,MKP电容两极接原两电解正极位置?
7.1.2M 东京光音 1%1/8W 电阻5 个, 更换R661、662、655、656,一支接SM5872的1和28脚
9.14K 1/4W 1% 电阻4个 更换R611、612、605、606
10. 430p 电容器 2个 更换C605、606
11. 470uH 电感 2个 更换L601、602
13. TXC 16.9344 Mhz 晶振 1个 更换XD01请问晶振是不是不分脚的?
14. OPA2604AP 运放 2个 更换Q605、606
17. 150pERO 电容器 2个 更换C659、660
18. 10p 云母电容 2个 更换CD03、CD02
19、220U电解 更换CD05
20、47欧姆 飞利浦 1% 1/8W 电阻2个 这两个电阻没看明白装哪里,请各位指教。

昨晚把晶振也换了,现在就只有7805换78S05未换(考虑到网上买的78S05说不定质量不稳定,决定此件不换了),至此此机已经全部改完。声音很通透,但感觉高频似乎有点过,中频似乎有点薄,也不知什么原因。哪位朋友能够指点一下?耦合电容用的这个(一边两个)http://trade.taobao.com/trade/detail/tradeSnap.htm?spm=a1z09.2.9.66&tradeID=171111279142696,主滤波用的这个(不知是否水货)http://trade.taobao.com/trade/detail/tradeSnap.htm?spm=a1z09.2.9.189&tradeID=202110644762696。谢谢!

昨天收到RS公司买的2604,跟市面上的完全不一样。区别如下:
市面买到的:1、白字,字体工整 2、字体笔划粗,但不模糊 3、脚上锡 4、用手擦字体,字不掉色。
RS买到的:1、黄字(暗黄),字体比市面买到要小 2、字体笔划细,感觉有点随意 3、脚无上锡 4、用手擦字体,有个别字掉色。
上机的区别更是大,大家买运放要多留心了
