Shigaclone MKII Black - The builders Thread
 
I am starting this thread to discuss the construction phase of building an Shigaclone MKII Black CD player / Transport .
I will post photo of building and some modding I will do on this board.

I need to solder first all SMD components .
Then after finish SMD solder I take the first IC .
If there is to much solder I use some braid to remove excess .

Then the next IC and on the other side again solder solder solder...
The display/LCD board have a strict order of solder :
first connector ( or ribbon direct if you do not use connector) and then other components.
Then we solder the power board and then testing .

Modding phase

I have some favorites modding on to do list :
- C8 = 100nF Silver Gold Oil Mundorf
- Clock Tentlabs Low Jitter 16,934Mhz (this means out with C57 ,C58, X01) and solder L8
- V3 and V4 miniregs , out with L9 ,L5 , solder wire for 2 miniregs
- C10 = Oscon Sanyo 270uF/10V
- C13 = Nichicon VR(M) 470uF/16V
- R48 , R36 Naked Vishay Resistors
- C11 1nF silver mica

Next I will build a case for this CD player .

Nice work Dan !

Here is how to build a modified power supply for Shiga MKII.

I'll start with tools I use.
Two tweezers, one for 1206 and one for 0805, flux, different pincers and solder pump.
My preferred solder is Mundorf silver-gold and I use only solder with high Ag percentage and very good flux. Cynel is also good one - SN96A-0.5/0.5 CYNEL - Solder | TME - Electronic components

You will need also a magnifier lamp, soldering station and optional rework station.

Regards,
Tibi

The parts I use for modded power supply.

Instead Soft recovery diodes MSR860 proposed by Peter Daniel, I chose to go for Silicon Carbide Schottky Cree CSD1060A. To my ears these offer a smother and more fluid high register.

The power supply board offer the option for two regulators, standard LM7808 and LT1086Adj.
Beside lower noise and excellent current capability, I got more detail with LT1086Adj, so this is my first choice here. LM317 is out of discussion here, performing under standard 7808, so don't waste your time.
As Black Gates are history, for primary 2200uF cap my choice is Panasonic FM decoupled with an oil cap. I used Russian PIO with great results, but new Mundorf EVO series are quite amazing, compact and performing very very good. Any HF spikes and noise are very nice cleaned.
You can get them from partsconnexion. Very good value.

For output cap my choice was Elna Cerafine decoupled with a 1nF silver-mica. The cerafine will provide excellent low esr, stabilizing LT1086 regulator, while 1nF silver mica, with his ultra low ERS/ESL, will clean further any HF noise.

IMHO this is the most cost effective power supply who will sensible improve your Shiga MKII.

Tibi

Always SMD parts first.
And now ready to move further with main board modifications.

TBC.

Yes, I started with the SMD resistors. The 100R ones are missing but I rather take that thru PM or in the GB thread. There were a bunch of SMD capacitors without markings so a LCD meter seems to be a mandatory tool :( I will take these last and solder in the ones identified first to see what they are meant. Maybe they are the same value all of them :). Otherwise - marvelous quality.

Case will come

Gone to some little enterprise from my town and got 2 plate : one for cover and one for bottom .
Like in pictures .
Also i buy one piece of wood of 10 cm wide , 2,5cm deep and 2 meters long .
Must now work to do front panel rear panel and rest.

If you are missing 100R resistor than means all other kits are missing this part too. :scratch:
I mentioned several times that a LCR meter is mandatory to finish SHIGA MKII.
On first SHIGA GB I did my best to mark all parts. People started to solder these without measuring and switched 3,3nF with 33nF, 10nF with 100nF and other parts too. This lead to non functioning kits or malfunctioning ones.
So, I decided do not mark these parts and force you to measure them. :devily:
Please measure resistors as well, because 3300 is not the same with 332.

About LCR, I personally use an Amprobe 37XR-A. This is same with Meterman 37XR-A.
