Not sure if anyone here can recommend something I haven't tried, but a relative had an Arcam CD72 he really enjoyed the sound of which had basically degraded to the point that it couldn't play a single disc without skipping constantly. Silver discs, CD-R, brand new, old, etc. didn't seem to matter. It just couldn't hack it. He passed it on to me to see if I could find anything to do with it. The innards were clean and the optics didn't have any visible issues. I picked up a new laser assembly on eBay and replaced the thing, but the problem persisted even with new optics, so it's clearly some kind of calibration issue, but that's beyond the scope of anything I've done before. At this point, there are three basic options (as I can see it): 1.) The optical assembly I used as a replacement was defective garbage and the problem isn't really "persisting" as much as not resolved by the replacement with an inferior part; 2.) I can learn how to calibrate the optics myself or find a shop in the northeastern US that can do the same; or 3.) Some unknown "X factor" is causing the issue and I've been barking up the wrong tree all this time. Anyone here had any success troubleshooting a similar issue? I gather that directly contacting Arcam isn't an option anymore as these are no longer made (or serviced?) by them directly.
