Mmm, who knows. But it made me take out the box with cdm's and make a picture.

CDM12's rescued from Hasselt. Some could be proto's

12.1/05, 12.1/15, 12.4, 12.9/51

Think i have one more in a loader.

all versions use the hologram laser diode with TO-outline (clearly to see at the photo except by the CDM12.9/51)

the currently available CD-Pro2LF/VAU1254/31 uses still the successor of Sharp's hologram diode LTOH30PA (LT0H30PA) as I have see by new devices.
Photos of this laser diode you will find there:
Stripdown/Clean of CDM12.4
As to see there, the outline is a TO (round) version and not resin version
in the attachement both outlines.

The only question for me now is, from where comes the hologram diode successors (of Sharp's LTOH30PA) inside by the currently CD-Pro2LF/VAU1254 devices?

Hi tiefbassuebertr,

I can bring you some clarifications about a few various mechanisms/modules you mentioned:

VAM1201/VAM1202: the VAM1201 had been officially discontinued a long time ago. The VAM1202 had been officialy discontinued a few years ago. It might be possible to find some copy of these mechanisms with very poor performances in terms of reliability compared to the original mechanisms.

VAM1210: there is no VAM1210: you probably refer to the L1210, a complete module (loader+ servo board without DAC section) that makes use of the VAM1202: Officialy discontinued

VAM1250: Philips mechanism which is still in production (look at the latest Vincent CD player)

VAM1205: as far as I know, it had been discontinued a while ago

VAU1252 = CD-Pro, previous version of the CD-Pro2LF (VAU1254/31LF)

CD-Pro, CD-Pro2, CD-Pro2M, CD-Pro2LF/ All the pevious version of the CD-Pro. The latest version is the CD-Pro2LF and is still in production and used by many manufacturers. You can have a look to this link to check the history of this module:
FAQ


I hope it is helpful for you
