I am looking for CD player models from Philips/Marantz, where the above mentioned servo unit is in use.
The only model, that I have found from Philips is the CD-670 - go to
http://egirland.blogspot.com/2013/03/again-on-philips-cd670-and-cdm2-cd.html
In the meantime I have find out, that this PSB's can be only recognized by the 4-digit number on the attached sticker mostly glued on the surface of TDA5708 and not by the above mentioned PCB numbers - check out the attachments in post #29 under

Unfortunately from several PCB's sticker with this number isn't longer to find.
Thank you in advance.
P.S.: this isn't mentioned there:

Yes, exact this boards.
I want to have a Philips CD player equipped with this boards for replace my faulty device from my Micromega "SOLO" in a Philips CD Player for repair and maintenance (focus servo and laser power adjust). This isn't possible on the "SOLO" itself.
Philips CD640 is a good advice. Most models with CDM1-4 have the same circuit, but integrated on a main board,. i. e. no extra PCB therefore

Thank you - if I have the associated service manual I will send a PM to you for an offer.
The CD640 and various other models (which I want to know) should actually point out which supplement for the service manual is necessary.
Such a supplement exist for the manuals of Philips models CD371-CD373, CD471-CD473, CD771, CD782, CD1371, CD1471, FCD760, FCD762 and FCD465 so as the Marantz models CD873, CD65DX, CD75DX - go to the third last page under
https://www.hifiengine.com/manual_library/philips/cdm-2.shtml
The associated mechanism is the C.D.M. -2 and the associated servo board is this one: "3104 103 34100 / 8204 054 17001"
similar but not identical to those from Micromega - mentioned above.
Now the question: do I need the service manual for the CDM-1 MK-II or a specific variant of the CDM-4 as supplement for the Philips CD-640 ?
If yes, who can upload this (I don't find it online) ?
Thank you very much.
I asked the wrong question here, which cannot be answered in this way because the service manuals do not mention any PCB numbers - go to post #29 unter

I understand CDM1 Mk2 is just a CDM4 with the hall drive motor of the CDM2. In some service manuals there are added service bulletins which explain the process to switch the electronics (the boards mentioned here) to drive CDM4s as at some point CDM2 production was ended and there where only CDM4s available as a spare part.
Yes, but I only know these bulletins from the cd player models where the servo/APC unit does not exist as an extra PCB and has been integrated on the main board. Thus such bulletins must be exist also for the CDM-2 service manual, since reference is made to this CDM-2 manual in all models with an extra servo board (check out e. g. Philips service manual CD660/670 page 6-9).
I have found the schematics for the servo board 6105 and 5886 and the differences (also in use in the last series of Philips CD650/CD660/CD670) - check out post #34+36 under

but this I want to have from Philips - maybe a supplement of the service manual from CDM-2 under
