This is an auction for an ALPINE CDA-7846J TDA-5648. I checked its operation before listing it, and the CD and radio seem to be working fine. I haven't been able to confirm the cassette deck's operation because I don't have any cassette tapes. Please understand that this is being sold as a junk item. The defects I found are that the CD deck's OPEN button is missing. I used a wiper blade clip to open and close it. The illumination of the left button under the equalizer is either broken or never lit up; it doesn't light up. There's a chip on the side, as shown in the image, but it's not visible once installed. Please purchase this item with the understanding that it's a deck from about 30 years ago and may have various issues. It's a rare item, so it's recommended for those looking for it. This deck has the scent of the Heisei era, which is not found in current audio systems. Why not reminisce about the past with it?
