Default Servo PCB for L1210/65 (CDM12.1/VAM1202) from Daisy -where in use by Marantz (Schema)

I need a schematic for the Servo/Decoder PCB, which is in use in the loader L1210/65 from Daisylaser (for mechanism CDM12.1, VAM1201 and VAM1202) - go to
pictures
Daisy call this PCB as follow:
"New CD7 II (SAA7327) servo-decoder for improved playability and reliability"

I read follow numberings on the PCB from Daisy (have a look to the PDF images):
1) HECD-019A
2) DN24A533

about
http://www.homecinema-fr.com/forum/v...1403&start=345
there are additional informations, mostly unfortunately in french language.
about
http://www.jacquesstompboxes.com/oscillo.htm
are to find the predecessor of this servo boards at a CD722 from Philips (scroll down).

There was produced several top class cd player in very small amount, where this PCB is in use. AVI (lab Series), RESTEK (Mini Pla), Northstar and various models from Micromega are examples.
Here some links of such brands:

Philips VAM 1210

Unfortunately this PCB isn't in use in Philips/Marantz CD Players like CD710, CD722, CD63 or CD67. Thus the service manuals are not helpful.

Who knows brands, which have produced cd player in large amount where this servo board is inside (like Marantz) ??

Such brands must actually publish the schematics (in opposite to DaisyLaser).

Thank you very much for advices

Default HECD-019A

I am tearing my hair out trying to identify transistors T905/904/906 & 907 on this PCB. It is out of a Cyrus CD6 CD player. Also require a schematic. Can anyone help me? There is no DC on the tray motor when given the open/close command.
David.

Default SERVO

Thank you for this helpfull information. My friend who owns the Cyrus CD6 player has decided to send it to the service agents in Sydney (Aus). So that's one more problem I don't have to worry about. But your helpfull info was much appreciated.

Unfortunately no success until now.
The actually question is an other:
In which Philips/Marantz models (both CD Players , burners, ghetto blasters and Hifi systems) the same boards are in use?
If I know this, it is easy to get schematics and service manuals.
Maybe Cyrus and AVI know this - try to call and ask this question. My english is too bad for a call by phone.
