CDM-9 / CD-Pro2 CD 轉盤製作班 30-Aug Day 1
Please check the soldering method of1) R102+R103 and R202+R203
2) I/O socket.
Any problem, please let me know. would you provide schematics for whom attending this course? 謝謝大家參與CDM-9 / CD-Pro2 CD 轉盤製作班, KK 會在網上一步一步教大家組
裝, 請留意這一主題
下一堂課程前的安排
------------------------
9月1日至9月12日 - 大家在家中組裝電源板
9月13日或20日 - 提交已完成的電源板家課到HiFi Fever (大家可在兩天中任何一天2:30-7:00pm任何時間到來交家課, 但不會上課)
9月14日至9月26日 - KK 幫大家測試/Debug 電源板
下一堂日期
---------------
9月27日 (2:30pm 開始) - 繼續上課組裝機芯, 機箱
希望這樣可以有多些時間給大家做好電源板和免除上堂時Debug的煩惱. KK 並會在
9月27日給各學員組裝評語. 讓大家下一次可以做得更好.
如有問題請回覆.
謝謝
HiFi Fever 塊板和第一板改了嗎？ Photo,
PCB is same.
Upgrade parts is UPGRADE than the last time.
Some parts will not provide. A new parts is added....
We are continous improvement...... 大家留意:
1. 用公文袋載住, 上面寫名
2. 無焊的零件我不會代焊, 除非寫明原因
3. 不會代洗底板

KK sir
可否再影多一点組裝圖嗎?
怕一焊錯就PK啦～ :D
Thanks
Dyna 我唔太明為何焊法不同之前那種?(resister)
是給Pro 2定CDM-9焊法?

可否講長细少少及有關線路.
Thanks!
Dyna Hi Admin,
For those problems on CDPRO2/CDM9, without schematic seems hard to learning and figuring out the reasoning of components.
Pls HELP!!!!! KK sir~
KK sir .Can you tell mebelow location is useless?
R104
R204
R304
Because I still have one 121R dale .

DYNA,R104
R204
R304
NO connection.
Because I still have one 121R dale .
Please give it back to me.
There are total 10 Resistors need to solder into the PCB. Hi KK,
Its too bad that need to short like this for the R102+R103 and R202+R203 since aldy fixed soldering on last week.
Its too short for this 2 resistors becos aldy cut after soldered.
KK could you pls teach how to fix, i've been try but its really too short
to solder again like photos.
Btw., from the list that for C64 should be WIMA but just got the default. Shall we hv WIMA for C64! BBLEUNG,

// one method, buy another set of resistor. Need to check I have stock or not. I remember have.
Btw., from the list that for C64 should be WIMA but just got the default. Shall we hv WIMA for C64!
// Let me check. Hi KK,
Tks & pls let me know! KK sir.
Sorry trouble you again~
I have question below.
I checked my rice box have 3pcs LT1805CT is correct?
47uf os-con total 31pcs is correct?
IC302 the location is useless?
Thanks
Dyna According to your components list of ultimate version of CDM9, the value of resistor R310 (Coaxial) is R115.After I soldering all the resistors save for R310, I remain one resistor of which value is measured 100.08 ohm.Please answer me if this resistor will be soldered in the location of R310. Dyna,
Sorry trouble you again~
I have question below.
// No problem, you are welcome.
I checked my rice box have 3pcs LT1805CT is correct?
// YES, 3 pcs, it should be soldering on IC102,202,302 with isolated plate install.
47uf os-con total 31pcs is correct?
// Should be 32pcs. I will give you back 1 pc, no problem.
IC302 the location is useless?
IC 302 is for Clock regulator.
KK TTZO,
Balance output mode: (XLR socket)
R309 : 100 ohm
R310 : Empty
C66 : Empty
Un-balance mode : (RCA socket)
R309 : 470 ohm
R310 : 100 ohm
C66 : 0.01uF or say (10nF)
If we supply a wrong resistor or your resistor is wrong value, please let us know. K.K.
I want to know how to install IC1 (LM317T), IC102 (LT1085CT), IC202(LT1085CT) & IC302 (LT1085CT).Now I have 4 coolers (1 small & 3 big), 3 screws, 3 rings & 3 導熱方形膠片.Pls let me know ASAP. K.K.
Do I have to solder resisters to the copper connecting points on both of top & bottom of the board ? TTZO,
IC102, 202, install on large heatsink, need to add isolated plate and plastic ring by M3 screw.
IC303 install on small heatsink, need to add isolated plate and plastic ring by M3 screw.
IC1 install on large heatsink, no need any isolation tools
Those heatsink have a 2 pin guide pin, need to fully insert into PCB.
For the soldering, only 1 side is enough. The PCB have plate through hole, which will connect top and bottom side.
