Ticking noise in Audio Research Reference CD7

Thanks Elizabeth, I'll check this out and report back.

Hi Elizabeth, I've opened the unit but can't see the rails. Do I have to also lift the CD tray to access those?
Is there anywhere where this process is described with pics for my layman self?
Also, I live in a very big city and there's a lot of dust/dirt/smog in the air at all times. How do you clean the guts of those units (CD 7, Ref 5, etc) that have practically no protection from all that dirt?
Thanks.

Did you expose the mechanism completely ? You need to take the player's top lid off first, then the square black metal element that covers the mechanism (it is beeing hold by 4 screws), and then the black plastic part that covers the rails (it is beeing hold by 4 allen bolts AFAIR).

Loud and clear.
I'll do just that.
Thanks.

Amuseb, I used to own the CD-7, and now the 8. If you check my System, I'm all ARC. I strongly recommend that rather than take the unit apart and fiddle with stuff you probably know very little about, that you call Calvin at the factory. He's there to help folks who own ARC gear. He will be able to diagnose the problem and advise you on what to do. It may be that the unit has to go to a service center or back to the factory. Dunno -- but Calvin will.
