Where the red arrow to point is that the plus (+) side?
I would like a confirmation because I make my own black and red cable.
To everyone, remember to mount the heat sink ...

Yes, exactly, your arrow indicate +8V and is also marked near on J6.
With a multimeter you can easily check that other pin is ground by testing continuity with LA6541 heatsink.
On Shiga MKII LA6541 do not require a heatsink. You do not need to put one as LA6541 will dissipate in the double ground plane we have calculated and designed.

Tibi, I see that ADP151 is missing in some photos. Should it always be used? Thanks.

ADP151-2.5 is optional. The sound get better with ADP151, but will be stable only with ultra low ESR caps >=1uF before and after.
SMD 1206 1uF is only in X7R and will exhibit measurable piezoefect. So, if you mount him, you need to take extra care on pcb vibrations.

I always test first the power supply if there are 8 volt comes out and yes I measuring 8 volt
But the diode (MSR860) and the capacitor is way too hot.
Please tell me what piece is defect?

When careful unpacking I noticed that the display falling apart, see picture …
Also the board connector looks defect, where the ribbon cable of the laser comes in, this can never have worked :( see picture …
Tibi please tell me wat to do, must I sent the whole unit back?

Regards,
Rudy
