Cleaning the laser, advisable?

I've heard of similar stories to Flex's. If the "brush" is relatively stiff, it can literally knock the lens off of the laser. This probably just sped up the process though, as the lens would have had to have been coming loose for this to happen.

Out of curiosity Flex, what happened after that ? Any help from the manufacturer ? Sean

Sean, once the disc was removed, the player recovered and has been working without obvious sonic deterioration for the last year. I decided to leave well enough alone, but I agree with your basic idea and should send it in for a health check of the laser assembly.

I have 508.24 as well and recently asked my local Meridian dealer what was the recommended method of cleaning the optics. He uses and recommends canned compressed air. However, I have used an Allsop Carbonedge Laser Lens Cleaner on a number of players including the 508 and it hasn't caused any problems. As a matter of fact it has helped with mistracking problems and improved the sonics in some instances. The apparatus is in the form of a compact disk with tiny carbon brushes attached to the data side. The one I have also has a track of pink noise for burn-ins, as well as other diagnostic tracks.
