V3 power XO, internal Pierce oscillator and internal VCO.
If miniregs are correctly implemented I do not see any reason to not work.
Help me with some pictures to help you.

In this case you should look on soldering or some other things that may happen - maybe a shortcut ...
Also, ribbon cable is a very sensitive one - check carefully.

Got the problem fixed last night,that one Wire had no good Contact. Listened to a couple CD everything ok. Left it on till now and it plays every Song for like 30sek and than stops.
What can I do ?

Shiga MKII is a SMD board and some precautions must be taken when you want to intervene and change parts or perform upgrades.
Antistatic workbench, proper soldering station, at least 3X magnifier, different tweezers are few parts you need before start to work on it.
I do not want to discourage experimentation, but without proper tools chances of destroying the board are far greater than any chance of success.

Had it off Mains for the Night and today it played one whole Song and stops. Than I put another Sanyo in and it plays for 1Hour now. I wonder if this is the same behavior that Erik got ,when he was talking about Problems.

Check distance between turntable and optics. This may be altered when you press to hard on CD puck. After correction, use a drop of glue under turntable to fix this.

Connector oxidation ?! Use a cleaning fluid an after that a contact one. I posted in this thread which one.

Can`t be it works with the other one.The funny thing is I only unhooked it,put the LDO`s in and it worked short Time normaly.

Whatever ... As long the unit is able to read TOC and play first 30sec, it is a mechanical issue.

Hi Tibi,
Please see attached picture of my mkII board. I will be installing the high grade parts as per your recommendations. Would you recommend upgrading the following caps:-
1. C32 - polymer ? which one?
2. C27 - tantalum?
3. C20 - polymer ? which one?
4. C48 - tantalum?
5. C2 - tantalum?
6. C51 - tantalum?
7. C52 - tantalum?
8. C13 - polymer? Nichicon PLF1C471MDO1 ?
9. C23 ?
Do I need to add C59 (10nf 50v) if I use Tentlabs crystal? What about R47 ?
Thanks for your help.

Hi,
1. C20 & C32 ULR107M1CE11 X-CON - Condensator: polimeric | TME - Componente electronice
2. C2, C27, C48, C51, C52 T350G106M035AT KEMET - Condensator: cu tantal | TME - Componente electronice
8. C13 leave as it is
My suggestion is to focus on things that really matter. Changing all caps will not bring the improvement you may expect.
Change C19 with a good quality one TAP476K035CCS AVX - Condensator: cu tantal | TME - Componente electronice
This will not bring immediate improvement, but C19 is part of laser CCS and the life of unit depend on this.
Add C11 - 1nF silver-mica CD.
Follow all modifications I already mentioned here http://www.diyaudio.com/forums/digi...mkii-black-builders-thread-5.html#post3929209
For Tentlabs you need to install L8, R47, C59 and remove XO1, C57,C58.

Tibi

WOW Effect !!!
Yesterday I put those 2 Resistors from underneath the Transport.That was really a big Improvement !Voices and guitars are so much better,really wow.
Thanks Tibi,really good work.
