This is a YAMAHA integrated amplifier, the CA-800II. I purchased this unit previously as a refurbished item and used it until late December 2025 (I was using it until a few days before listing it). I am selling it because I have accumulated more audio equipment. Speakers A and B, both left and right channels, are working fine. I listened to records (MM cartridge) connected to PHONO1. (I didn't usually use PHONO2, but I checked it before listing and it was working without any problems.) I occasionally listened to CDs connected to AUX1. (I didn't use AUX2, but I checked it before listing and it was working without any problems.) I haven't used the tape function, so I haven't confirmed its functionality. Please check the photos for some scratches on the wood case. I used to own a CA-1000II, and this CA-800II also produced a pretty good sound. If you're interested, please consider it! * I purchased this as a refurbished item and used it without any problems. Please understand that it is approximately 50 years old before purchasing. Future maintenance may be required. (Personally, I think it's in good condition for its age.) * Please refrain from purchasing if you are concerned about minor details. * No claims and no returns are accepted. (Returns and exchanges are not accepted to prevent product substitution.) - - - - - * It is also being sold elsewhere, so there may be a discrepancy in sales. Thank you for your understanding. - - - - - YAMAHA CA-800II Integrated Amplifier Audio Equipment
