This is a BOSE PLS-1310 CD receiver amplifier. I received this item previously. I am selling it to organize my collection. I believe this model is considered a relatively high-end unit. I have tested its operation. The CD tray opens, but the digital display for the tracks does not appear when a CD is inserted, and it does not play. The radio has not been tested. Please be aware of this. External output has been confirmed to produce sound via AUX. I connected a phono equalizer and was able to get sound from a record player without any problems, so I believe it can still be used as an amplifier. The sound was quite good! The main unit has some scratches and dirt. There are also paint剥がれ (peeling) and dirt on the buttons and other areas. However, overall, it is in relatively good condition. Please understand. Because the CD player does not work, I am selling it as junk. Please consider this item if you can repair it, use it for parts, or perform maintenance yourself. I will pack it in bubble wrap and ship it in a cardboard box. Please purchase this item with the above conditions in mind. Please understand that this is a home-stored item before purchasing. #BOSE #HighEnd #Amplifier #ReceiverAmplifier
