I can pretty much guarantee that the laser head will not die. They are bombproof!!!
The cd drive spindle motor however is probably near the end of it's life and replacements are not available. You would be better advised to look for a CD5500 which will prove more reliable.
I suspect that you are also asking if you can connect 2 cd players to the beomaster? Yes you can and I would plug in to the tape input with a din lead.
