I can't believe it's a sound investment to put any money into the CAL, because the transport will give out sooner rather than later, and then it will be unusable. Better to invest in something new(er).
So general advice w.r.t. that and other components: start new thread(s) posing specific questions in new terms. E.g. looking for new or used CD player between $X and $Y. OR: recommendations for someone to refurbish my amplifier manufactured by ABC.
