This is a cassette deck released by SONY in 1987, featuring a 3-head design and a closed-loop dual capstan system. The original price at the time was ¥85,000. The cassette door hinge was broken and has been repaired by embedding screws. It is believed that the hinge broke due to the impact of the door opening forcefully, likely caused by the deterioration of the damper O-ring during cassette door opening and closing. The deteriorated O-ring has also been replaced. The capstan belt was loose, so it has been replaced. The BL motor for capstan drive is quartz lock servo, and tape speed was confirmed to be accurate. The record/playback heads are independent suspension laser amorphous heads, and the original heads are installed. There is some wear, and the surface has been lightly polished. The head azimuth was checked, and there was not much deviation, so it has been left as is. Recording and playback are normal, but the right channel appears to be about 0.5 marks lower during recording. It may be better to set the recording level while in TAPE mode during recording. The tape used for the recording/playback test (SONY HF90) will be included. The remote control and instruction manual are not included. There is a paint crack on the upper rear of the top panel. Please refer to the photos. It is currently working, but it is an old used item, so please consider purchasing with no claims and no returns.
