Cary audio cd303t problems

Totally different, what the OP has, his is a 3 beam dedicated CD/SACD laser very different. What you have in the links below for the 303/300 is a dvd rom drive and laser in yours a DSL-710a. I can imagine Cary asking a lot more if they have his in stock.

Or the complete drive.

If it was in a smoky/dusty environment, then a laser clean could fix it. If this doesn’t then a new laser could be in order.

It seems from my data it uses the same laser that is in the Sony SCD-1 which is a KHS-180A.

Oops: I just clicked on those and they're all used, which may mean expensive new if available, or not made anymore.
