I need a new laser assembly and a cd mechanism for an Adcom GCD-750. I am told the parts ceased production this year. Their part numbers are 42001050 and 420000753. Any ideas where I can get these?

Thanks for your suggestions. However I am using carefully boxed clean CDs and the skipping is on all. The Laser glass is clean. Since submitting the problem I removed case and the CD is lifted off tray by a lift motor which has a round nylon top on the shaft which "sandwiches" the CD against a freely rotating plastic piece in a lipped cylinder container. The lift motor then rotates the CD which is read by a separate fixed laser. My current suspicion is that the CD is slipping inside the rotating "sandwich". Hopefully someone who has worked on an Adcom GCD 600 can suggest a fix.

Back in the late 1980's the GCD-575 was about as good as you could get in CD players. Today it likely can still hold its own when rejuvenated to original operating condition when it left the factory (but can't play SACD's hires layer). Main problem... deteriorated main board soldering, a few hours with a solder sucker, (best to resolder use 2% or 4% silver solder everywhere) and replace 32 year old caps, and this set should equal the sound of a mega-buck player (also change the open/close belt). Modern caps are likely smaller so a 2,200 can be replaced by a 3,300 or 4,700 uF. part at the same voltage, etc. the output cap value should be doubled, and a bipolar used, or bypassed with a polypropylene or Teflon, IIRC plenty of room is available inside the case for either (or both). That is a lot of work. Well worth it. -Steven

Kind regards

I thought it used a KSS-240 which is a Sony laser.
# will be on the laser and Mcm has it for I think $35

For the owner's manual for this legacy(old) unit go to;

For $350 you should be able to buy 5 new units- at least.

It will require a tech to open and clean the laser lens and change the drawer belt.

Hi mate,
I experienced this problem awhile back with mine. I had it serviced and the techs couldn't find anything wrong. They cleaned the laser and lubed the tray and sent it back. To my dismay, the problem re-started shortly after arrival and then stopped. By coincidence, I had just finished a home theater set up "that did not have wall to wall carpeting" and low behold the problem stopped and never re-surfaced. I summed it up to static charge/discharge which might also be your problem.

I hope that helps.

Is there a specific question or just generalities? Open up the top and the Sony optics number should be right on the optic assembly. I believe that it uses a KSS-240 optics assembly. What else do you need?

If I understand your issue, you press play and the player does not recognize the disc, the optical pickup may be defective. I suggest you contact an Authorized Adcom Service Center. For further questions, contact Adcom directly.

Are you sure the fuses located on a PCB below the opened drawer are all OK? Otherwise you likely have a mechanical issues and I suggest you contact an Authorized Adcom Service Center. For further information visit www.adcom.com and contact Adcom. Affiliated Electronics in Hillsborough, NJ, may be your best bet as they have salvage Adcom parts.
