Admin SIR你好, 請問有沒有LS-7KITS 和機箱? 如有的話我也來報名.

LS-7KIT 有, 機箱都應該找到.. (你報名後便先幫你訂)

真的唔該Admin SIR, 我會在星期一, 入數到貴公司指定人名的渣打銀行的賬户,然後再通知你好嗎.
再有一個問題想問? 會不會有 VT60SE 後級課程開班, 和CD機製作課程, 因我想親手製作一套HI-END音响來作紀念和一個夢想, 所以才這麽多問題打擾Admin SIR你, Thanks alot.

Hi Admin大大/Modi Sir,

可否當天取回我的300B Mono?  另外想問有否EL34的后級/合併kit set?

martin88, VT60 仲有兩套散料, 可以和前級一起砌 (當然要modi Sir幫手才可以夠時間完成)

CD 機可能要等新年後了...

Cyrus, 當然沒問題!

會問問modi Sir有沒有EL34的線路 / kit

Hi Admin SIR , today i save deposit to your account for the december course, and FAX the deposit slip for you, when you have time, you check it. Thank alot Admin SIR, have a nice day.

Hi martin88, received, thx

你好Admin SIR, 我想定購 ARC VT60SE, 請問是不是VT60SE 版本還是VT60 版本? 可否和我聯絡, 我留電話 PM 給你 Admin SIR, 有空時間請覆我,唔該晒你, 謝謝你.

martin88, 是VT60SE.

CD 機可能要等新年後了...

I will setup the Prototype (With Full option, Ultimate Version) in hififever.

Audio amp classmate can listen what kind of performance is....

See you 新年後

THX.

你好Admin SIR, 已收到前後級部分layout, 在這好多謝幾位老師的意見和講解, 小弟一定做好功課給幾位老師評分和指導, KK SIR 如日後開製作CD機課程,記得通知小弟, 我會第一個報名. THANKS 幾位老師

我想報名, 但係想知係未要買料 ?

如果係 咁係未 膽前級/後級/合併機/耳擴 d 料刀要買晒?

如果係大約要買幾 $ ?

課程的第一天決定要做什麼器材，並不是所有機都做，除非你要求要做齊所有機，多數只會做一部機的，要視乎你做什麼機，由千多圓起的耳擴去到有學員做後級幾萬圓也有，要視乎自己的能力。

你好Admin SIR, 小弟有幾個問題想你指教, LS7零件表有個叫做 D6 (IN5535), 應該是15V穩壓二極管, 找不到, 只找到一個叫(BZX55C15 ST)二極管,現付上圖片 是否這個就是D6 (IN5535)? 和在LS7 PCB版上的(BENNIC)電容共有7粒,可否換上貴公司售買的UCC SPP 和 MKP 的電容?音色會否好過(BENNIC)電容?如果是好過的, 有空時間請報價PM給小弟, 唔該晒Admin SIR. THX......

martin88, 不要焊接diode住.. 到時才焊接.

可以upgrade UCC, 我看看有沒有合用的..

好的, THX Admin SIR

你好Admin SIR, 小弟想訂購以下數值的電容 for LS7 & VT60SE
LS7 [(C9) 0.01uf +-10% spp 630v x3pcs]
      [(C4L-C4R) 2.2uf 400vj MKP 2000  x2pcs]
      [(C14) 2.2uf +-10% spp 400v x1pcs]
VT60SE
      [(C26) 2.2uf +-10% spp 400v x1pcs]
請問可否安裝這些數值的電容在這幾個位置?
想問一問在PCB版上有幾粒叫雲母和獨石是不是MICA電容, 可否轉用另外一些叫銀雲母的電容, 現付上圖, 如 27pf 數值沒有, 用22pf 定30pf 可以? 如有空時間請回覆唔該 Admin SIR THX.......

martin, UCC 應該有貨, check 完再通知你.

Thanks Admin SIR

martin99, I have prepared the UCC cap and silver cable for you, you can ask modi to get and pay for it on Fri night.

O.K THX Admin SIR, see you on firday night.

Jeffrey thx for joining!

cpk, thx for joining!

Will the course postpone when under 8 participants.

Thanks.

Hi Admin Sir:
Just paid this Course fee HKD 700(HK 714.00,Paypal). I think I'm the No.8 student!

I 'm new to DIY such a thing, hoping I can handle it well.

See you.

raceinfi66, thx for joining!

Hi William and Modi,

I'll assume the course will start tomorrow and will arrive to pick up my mono blocks, thanks.

Hi Modi sir,

I would like to construct an pre-amp with input selector function. Which kind of  selector will you suggest, simple mechanical rotary selector or electronic relay type?

可否明天即時報名交費上課
我叫TK Wong 電話61020969
謝謝！

今天上了第一課的膽前級/後級裝組班,令我加深了對音响的認識,看到大家在裝組班的熱充,令我感覺到學習音响的路是非常慢長,但是我覺得有好的導師指導下,一步一步學習便不困難,幸好在這課程有好的導師 Modi sir 和 William sir 教導才順利上了第一課, 真是辛苦了你們,在這好多謝兩位亞 SIR的教導. THANKS....

Regards
martin

謝謝大家!!

已完成的細膽機！

各位學員可於星期六16/01/2010早上1130時到HiFiFever繼續組裝機的課程，希望大家能準時出席。

Hi Modi Sir,

正在家中砌ANM7, 但想清教:
我自己做reg. broad(因提供的太大了..), 做好啦, 用洞板搭棚的, 星期六會給你check check....
但現在想學做 2 级稳压, (改進大嗎?), 但找不到線路图...請問, 用 2 粒LT1085來做, 那第 1 級 LT1085 之後, 要先接100u/200u 輸出 cap 去第 2 級,降压後再接另一组輸出 cap( 共 2 組)  還是只需要 1 組輸出 cap , 只放在第 2 級之後??

只想學習一下...又未必會整的.

有勞了..........

KK comment:

2 LDO in series:
Pos : If the input voltage is vary, you may need double LDO to reduce the noise.

Con : Double heat dissipation at 2 LDO.


2 LDO in Parallel:
Pos : Double current, less power dissipation in each LDO. highest performance and low noise.

Con : If the input voltage is vary many, the noise will increase.

KK choose 2 LDO in parallel. (but must be same brand) !!!.

KK@ Business Trip........

Hi KK Sir,

Thanks for your reply!!
Still lots of things to learn..
This time I just leave it one LDO, and find a way to make it cooler.

THX!

Anthony

Raceinfi66

2 or more LDO in parallel can share the heat (power dissipation) of each LDO.

Remember only Linear Technology (LT1085) describe this method, if you using another LM317 (NS, ON, etc), may not work perfectly.

KK.HO @ Biz Trip.

請大家於明天1430時出席制作班！

Hi Modi Sir;

I forgot to pack my drill bits set and leave it just next to the white broad.

I'm wonder anyone(host) will be there on Monday?? If so, I can come along and pick it up.
Thanks in advance,

Anthony

昨天是第四堂了，當中也有學員已完成自己的制作。
