I have a Bose Wave CD/Radio circa 2005
For the last couple of years, the CD player has been 'stuttering' when it commences playing. If I leave it alone, it corrects itself and plays fine.
Assuming the lens thing was dusty, I bought one of these cleaning CD's with a tiny brush glued to the playing surface and that worked after one or two plays. Then, the one or two became three or four, then seven or eight etc, but always next day...the same problem!
I got bored with the cleaner and encouraged by others' brave efforts at accessing the lens & cleaning manually with alcohol, I plucked up the courage to get at the insides. I had no idea what I was looking for, got scared, and put it back in the case.....BUT....then had an idea......If I couldn't locate the lens for cleaning....maybe I could deliver the alcohol to the lens VIA THE LITTLE BRUSH ON THE CLEANING CD! I did this using fine small water colour sable brush dipped in vodka, and the first play was disappointingly the same as before....stuttering again. Give up. Then a miracle! I tried it NEXT DAY: PERFECT! Again & again! Three days later is still perfect. I can only guess that the first trial after the vodka treatment failed because the alcohol on the lens thing was still wet which confused the signal. When the spirit evaporated the lens had been washed and is now A OK
Worth a try?
