It has been boxed and stored in a closet for the past 30 years or so, and recently removed and used. The unit was stored fully functional, but now exhibits the typical problems of older audio gear that hasnt been used in a long time. Cosmetically, the unit has surface marks typical of a portable unit of this era (1982). The back right corner has damage from impact and a section has been glued back together (theres a little section missing see photos). The battery compartment door is original (not a replacement), but the composition of material differs from the surrounding unit and has aged differently (appears lighter in tone). The AC power cord is flexible and damage free (its like a new cord). The telescopic antenna is complete and expands / contracts normally. The middle antenna retaining clip on the top of the unit is missing a small section on the outer edge (still holds the antenna when its retracted and stored). The unit powers on/off without issue. The selector for the radio bands needs to be cleaned as it affects the sound output (sound will cut out, and moving the selector knob to another band and back restores it most of the time). When I first powered it on after removing it from storage, the right channel was out. Not sure which of the knobs or switches is the problem, but moving them to different positions seems to affect the left and right channels i. Brings one back if it goes out. Currently, the left channel is out. I think the electronic switches and knobs need cleaning. For the radio section, tuning within the bands seems more audibly noisy in the higher frequencies (far right side) while moving through the stations. The DSL (Dynamic Super Loudness) system works, but the button that engages it needs to be cleaned or repaired. There are indications of two missing decals on the back of the unit. The label adhesive dried out and they fell off at some point. The narrow one on the left side was a caution about battery types, and the missing one on the right was a Tested by Underwriters Laboratories (UL) sticker. Additionally, the belts for the cassette mechanism have decayed and are no longer present (normal for a unit of this age). If play is pressed on the cassette mechanism, you can hear the motor rotating. The motor is audible, so it might be a benefit to clean or replace it. I have tested the RCA audio inputs and the headphone jack and they work fine. Im not able to test aspects of the cassette functionality or the other inputs / outputs, so for all these reasons and the ones listed above, Im listing the AIWA CS-500U as Not Working – For Parts. I hope someone does a complete restoration and enjoys this beauty as much as I have. Note: I no longer have the original box, but I do have the Operating Instructions book that came with the unit. Please see my other listing for the “Operating Instructions” (user manual) for the AIWA CS-500U, H, and HG models.
