You should just get a newer Rotel RCD-1572MKII, you can find them for around $1,200.00 or try to find a new older RCD-1572 I have 2 of them and I paid around $700.00 for each, just take your time and you can find some deals on demo models from many different brands.
Worth fixing?
I have a Rotel 951 CD player paired with an Arcam alpha7 amp and Paradigm speakers. One speaker cuts in and out occasionally. (Which doesn’t happen with the turntable). Swapped it with an Onkyo CD player and problem solved so it’s clearly the CD player issue. But it has some sentimental value. Ideas about what the problem might be and is it fixable by me. Or should I junk it.
