The ORIGINAL Sony CDP-101 CD player... includes original manual, service manual, supplement, warranty info, and an article from 1985 on improving performance. Everything appears to work except it does not output any sound. The drawer opens and closes, it accepts disks, starts to play, scans through, shows the time moving forward... but no sound from the RCA or headphone jacks. A video is at https://youtu.be/WEFj_XIGDhg
