Who know the CD transport from attached images ?

I saw one passing by years ago but I neither listened to it nor opened it.
Seen from here it looks like a disgusting clone of the Philips/Marantz player, not very advanced and without an output stage in a homemade box.
A strange thing is that the laser unit is mounted upside down (rotated 180°)

Looking quickly like this, it looks like a Philips CD 130/140 (cdm4/19) with a DIY PCB.
Can you have more detailed photos?

No, because I haven't this model on the desk.
The image I upload in post #1 comes from a member from an other forum - I get it via PM.
He want to have more images so as a schematic diagram.
I know this kind of the PCB from an other English cd player from those days.
According the images of CD140 main PCB from Philips under
https://www-audiovintage-fr.transla...tr_sl=fr&_x_tr_tl=de&_x_tr_hl=de&_x_tr_pto=sc
I note no similarity concerning the kind of PCB.
This Philips model use a usual kind, but the transport from ESTi use on their PCB instead a continuous copper surface (for the aim of screening) a grid-like structure.
I.e., no PCB for diy, evaluation and experiments, as to find in post #12+15 under

a currently device of this brand - on aliexpress lo longer to find

I'm thinking of the basic structure of the diagram of a Philips reader transposed onto a custom PCB by ESTi.
What could be better and simpler to obtain a nice result and if you also put it in a pretty box, you get something very sellable and nice to put in a window.

The grid effect is just the original ground plan but easier to implement.
