This is a 3-head, dual-capstan cassette deck released by A&D in 1989. It had a list price of ¥85,000 at the time and employed a Super GX head for recording and playback. I acquired this non-working unit a few years ago, which had lost its cassette holder. I repaired it by transplanting the cassette holder from a GX-Z5000. Therefore, it lacks the stabilizer to suppress cassette vibration, and the front cassette door has the GX-Z5000 logo. The mechanical components have been serviced, including replacing/correcting rubber parts, removing and reapplying grease to stuck sliding parts, and adjusting the volume for cassette holder opening/closing and head lifting positions. It is currently in working condition. The cassette holder opening/closing sound is somewhat loud due to the deterioration of the cam motor. Because the cassette holder and appearance differ from the original GX-Z7100EX, it is considered a junk item. There is no remote control. As this product is over 35 years old, it is currently working, but there is a possibility that the condition may change due to vibration during transportation or use. Please understand that this item is sold as-is, with no returns accepted. Please consider purchasing this item with the above conditions in mind. In addition, I will include the tape (SONY HF 60 minutes) used for recording/playback tests during the maintenance as a listening sample.
