I own an AIWA CD player (TZ92), 13 years old. In this time I have used
it about 50 hours (it was in my summer house), and I've changed the
laser two times, the first 6 years ago and the second this week. I don't
want to throw it, as it is part of a chain.

My questions a

- The life of the laser is related to working hours or installed hours?
- This short life, is normal?
- Is there any method for lengthening the life?
