Hi Troels,
The Northstar M192 from Italy and Polyfusion from the USA:
http://www.northstar.it/
http://www.polyfusionaudio.com/rvws/9801fi.html
Proceed I. PS Audio Lamda transport, Goldmund, MARANTZ CD 72 MK2 "Special Edition"
Found this on Hifi.nl
"I know I should have been already home now, but I take an extra moment to give an usefull tip here. A tip we often give to customers visiting us: if you buy a cd-player, specially if it is an expensive one, buy at the same time a laserhead for possible future repairs. It's better to make a small investment for a laserhead than discovering at a certain moment that these are not available anymore or extremely expensive. Think of the Philips CDM9-Pro which was used very often in expensive high-end machines. For people who have a problem because they cannot get a CDM-9Pro anymore, we might have a solution by the way. Contact us about that."

Hi again :)
You don't actualy need a replacement CDM-9 pro! Just swap the laserhead from a 'normal' CDM-9 to your old CDM-9 pro.
I got my info from Herman van den Dungen, DUROB AUDIO BV. |

Hi all
I have gone through this mission with my Theta Data as well as a friends unit.
Theta, Audiolab, Rotel (never seen myself but I trust the source who told me), PS Audio (made for them by Theta, different face and tray location) I think Marantz on the CD23 but I doubt the CD72, that is CDM4 I think. Several other high end type companies used the 9 pro. No mass market co has used this mech except Sherwood and Rotel and they were far from their entry level units that used it.
Arcam, Philips Rotel RCD970 and the naim units used the std 9.
If you have a laser problem, then just swap the swing arm and laser from a 9/44. Herman again deserves some credit here...
If you have a motor or spindle problem, you have a problem as this is the main difference between pro and others....... I have a spare motor (no spindle though) but you would have to threaten my life to make me part with it.
The 44 spindle motor shaft is also thinner then the pro so you can not swap spindles either.
What is wrong with the player you are trying to repair? If the laser is flakey on this drive, sometimes the motor does not spin to read toc. It made me think I had a faulty motor. Since the laser swap I have had no more grief, nor has my friend. Be aware that there are lower quality cdm9/44 units sold out there. One unit I got had no philips sticker anywhere and would not read CDRW but seemed fine otherwise, my philips branded unit does without a problem!!!
Regards

I can verify that. My CD72mkII uses CDM-4/19. |

.....it's working - i repaired it.....:D
it was the lasers thin foil cable that was damaged, one of the copper leads was cut in two.
i was really nervous that the krell was dead.....and now it's playing better than ever - i replaced all the caps on the controller/sevo board with oscons.
next up is black gates nx arround dacs and I/V opa's..... |

I have Theta Data BAsic II transport. Sadly, the gear that spins so that the drawer can open/close is broken. How can I get another gear? Theta has some but they are not only costly but are not original and thus was told by Theta that my drawer will not open/close smoothly.
Thanks in advance,
Gary |

The pro and 9/44 use the same tray gear. Philips used the cdm9 on the CD951 and CD931, choose which one of the two you would like to "own" and call your local Philips repair agent and ask for part number 4822-522-33192.
I ordered this way and got them here in South Africa (took 6 weeks) for about USD4.00 each. I believe this item comes in and out of stock at Philips these days but I enquired with a Dutch parts reseller about 8 weeks ago and there was stock. They wanted to charge me a huge handling fee, 3 times the price of the gear. The repair agent did not.
It is said that the grease used on the gear and tray is what makes the plastic brittle, so before you put in a new gear clean the tray thoroughly and use something non agressive like silicon grease. I used a little Wynflon. Teflon based stuff from Wynns.
The job takes 20 - 30 minutes, you will need a torx screwdriver set to remove the control pcb from the mechanism.
Good luck!!!!! |
