I wanted to ask you a question, do you know if the service manual for the servo board for CDM PRO Vau1252 is available? I have a problem with a Mark Levinson n37, the drawer does not open and close and the problem is on the servo board, there is some component short circuit.
I think the drawer is nothing to do with the CD-PRO, the DSA of CD-pro, even don't have the open close command!
CD6000 no need any DSA, the DSA controller also control the SAA ic by I2C, and convert the command to DSA for MCU.
Yes, exactly, the drawer opening and closing controls are external to the servo board.
However there is some "interference" between the servo and the player controller.
But according to the tests done by another forum user there is an anomaly in the board, there are 390 ohms at a specific pin that shouldn't be there, there is certainly a short circuit somewhere that creates problems with the drawer controls.
For whom could be interested Aliexpress sells this kit:

It's a beautiful servo board, DSA compatible for CDM12 OPU, could be purchased with or without controller and brushless motor and it's full functional!
