High-end DAC Tube (1541A)
Just ordered this kit from William. I will receive it next week hopefully.By looking at the picture that William sent. This kit doesn't come with Hi End components.
Any Suggestions to modify?
http://www.hififever.com/forum/files/t_sany0121__large__195_181.jpg 整理好些線吧！ The DAC in the picture is not mine. I haven'treceived the kit yet.
I am sure my kit's internal cable will not be a mess, 你大可以要求upgrade, 小弟都有upgrade
elna fine-gold, dale電阻, output holco電阻, output的一對cap, 自己可以點買都得 - 當然高速整流子
圖中一對藍色的output cap, 是那位機主自己買
線也可upgrade, 但建議大機箱先upgrade, 細箱太硬好惡搞
小弟o的線最後只可用軟身少少的mogami 2791+日本h字頭的ofc天線作同軸 Too bad William 己经寄出我的kit.
你的Upgrade 用了幾多錢?
可以分享一些pictures 嗎?
用什麼高速整流子好? 我有些 MR854 ad MUR1100.
Thanks
Bong Hi BongCalifornia,
你可以把 Tube Buffer 改成搭棚製作，參考相片如下: 嘩, AP 兄, 去邊處買到咁多銅片?
CAT 那两只JENSEN电容，是不是要超级恐怖的价格啊？ 300元一隻左右。 300元一隻左右。
哦，都不便宜啊。
看到有商傢賣JENSEN電容，1U左右的都要4000～6000元人民幣一衹呢，真是嚇人哦。 嘩, AP 兄, 去邊處買到咁多銅片?

alfcat前輩, 是在新填地街執的散料，大約HK$40~50/磅。 300元一隻左右。

Jensen 的電容有很多種，你說的是全銀的。不用那麼貴吧！ Dear AP,

這條街真是寶物多多.... 得閒我都要去看一吓. 請問近那一面?

AP SIR (你的新名稱): 小弟關心的是那一家願意賣少少料 :?:我正為我的第二隻隔離牛的銅板做底座頭痛到爆...可否pm小弟exact位置
諗起今日開放日有點失落 :!: 因發現隔離牛 / dac都有新版本, 舊人好似...唉, 只有長長嘆一口氣
唯有安慰自己 - 早買早享受 :!: 嘩, AP 兄, 去邊處買到咁多銅片?

呢個世界就係咁樣,我報左今次DAC&CD機,但到下次是我們感到失落呢... :) Sam Sam,
1. We should improve... V1.0, 2.0, 3.0, ......
2. We will review each course and the feedback from customer.
3. We will have some upgrade service for early customer who have V1.0, 2.0... just like what I said that to you.
4. A lot of new course / model should be adding to DIY course.
(I think you also not happy to see every time is GG...etc)
5. Continous improvement must need.
Chicken Sir I am building this DAC.
I have a question about the Oscillator.
Should I use 1K or 475 for R25?
For C33, use 0.047UF?
Should I assembleC35? Wherein the Digital board should I connect to the tube buffer?
I have this kit sitting around for almost 1 month.
Very hard to get support!!!!
Please help.
I need to finish this kit.
Thanks,
Bong Bong, As you use 8414
You should use 470ohm and 0.068uF, C35 no use
For tube buffer, simply connect the DAC IV output (the first NE5534 output to tube in) Bong,
CS8414 PLL filter.
R25 --> 470R
C33 --> 0.068uF
C35 --> No component.
I/V conversion connect to Tube buffer in.
Face to the PCB, please find R19 resistor (2K)
The left hand side of the leg is the I/V output of Left channel,
connect it to tube buffer left channel input
Find R21 resistor (2K)
Left hand side of the leg is the right output.
The GND signal (typical is a shielding wire)
Connect L GND wire near C45 GND position
Connect R GND wire near C55 GND position.
Hope can help you, any question, please email to me.

Sam Sam 哥:
咁多阿 sir 响度你叫我 "AP SIR" 真係唔敢當!
舖頭的位置大約在紅圈的位置，但唔係好肯定，印象中係响個公園仔附近。確實地址我要 check 吓仲有冇印咗佢地址的單响屋企先知。
佢都唔係 exactly "願意賣少少料"，我買的只是散料，即是賣剩的頭頭尾尾，自己度過呎吋同厚度OK就比老板磅吓幾多錢。另外買銅 bar 佢都肯開料賣比你，但係準確程度同切口美觀程度就唔可以要求太高喇。
至於你想買隔離牛的銅板機會比較眇茫，因為老板話厚過一分o既銅板要成件(床板咁大)買呀!
