Thanks so much for doing some research on my behalf. Unfortunately, though they bear some similarities, neither of the options you discovered are drop-in replacements for the Philips laser in my Cary CD player. Cary has a cast aluminum disc tray that will only fit with a specific Philips laser. I have posted a link to a photo of my current laser below so you can see the physical differences between the various laser assemblies. Thanks again for the effort.
