Shigaclone MKII Black - The builders Thread

Hi Tibi,

Have a read over and over to all the post, skip, fast, get what I want. I need to clarify few things from you and some are very silly questions. I am sure I am missing something here.

1) C8, as in your #28 says ' standard at 0.1uf and recommended 10uf for tantalum. So 10uf is only refer to tants?

2) # 25 of c66 prefer to use silver mica 1 nf. So 1nf = 1000 pf? I only know uf. PartsX is selling too right?

3) Please refer to the picture that I have a spare Sanyo cap from DAC. Since I follow you to buy Cerafine for psu output, is it fine to use this for the front part? or should I still get Panasonic? I see a tants in your psu.

4) #50 of C19. I cant find the BG VK selling anymore in PartsX. did I missed out? Otherwise, I read you prefer Tants, as that had mount on my pcb. To the picture, I have Cerafine and Silmic 47uf. Tants still better?

5) To the far right cap in the picture, very small but I have no idea what brand. I plug it off from my DAC too. As I read again, you mention any cap can do good. This looks okie to you?

6) The icing thing. 1nf to 2n2f = 1000pf? to 2200pf? Please help to give me the parts number in PartsX.

Last, why so many tants? I don't have a good experience with it because: I recap my naim 32.5 all tants with Wima and detail is a lot better. Or maybe the tants are too old. Please enlighten me.


Thank you again.

Alfred.

Alfred,

Short answers.

1. C8 must be 0.1uF I don't know from where you got 10uF. Use top quality here like Mundorf SGO or Duelund Cast.

2. yes. 1nf = 1000 pf

3. use parts I recommend. Don't put anything you have in the bin

4. C19 use tantalum if you don't get BG

5. ?? Ok for what ??

6. capacitor_film_smica.html
code SMICA-54435

Use the right cap in the right place. Tantalum are very nonlinear in signal path, vary bad for analog decoupling, but very good in digital decoupling, where low current leakage is required - for example CCS - , long term stability, etc ...

Tibi

Dear Tibi,

First off all, hallo to you and everybody on this forum.
Tibi some parts to upgrade the MkII motherboard arrived today and I noticed I ordered for C8 a Mundors Silver Gold 0.15 uF instead of 0.1 uF. Can I use the 0.15 uF or should ship it back and try to change it with a 0,1 uf version?

Regards,
Robert

Hi Robert,

Please use 0.1uF
0.15uF is far to high and tracking will be very slow.

Music is there!

Dear Tibi, Aleks and the others,
I finally was able the correctly cable between J2 and the transport. This changed the picture drastically.

I have music!

Status is:
1. Transport works properly.
2. Display shows partly nonsense. A part of the buttons work.
3. LA6541 temperature is about 52 deg C, i guess it's fine.
4. I did not resolder any chips since last weekend.

My next step is to check the connector J10 or some pins in the direction of LC78601.

Thanks for all help provided in the last weeks,
Paul
