Gonna be listing my vintage AIWA JX303 soon on eBay.  This is the Japanese version, which makes it even rarer.  Overall, it's in really great condition.  Cosmetically, I'd consider it mint.  All accessories are in really good condition and working as well.  AIWA Travel Case, AIWA headphones, AIWA remote control, AAA battery adapter connector, and AIWA power cord.

However, the unit will require a tune up from your electronics service technician.  I believe the capacitors will need to be replaced, as their is a buzzing in the audio when you play the cassette.  I've read that capacitors were an issue with vintage AIWA walkmans.  Should be an easy fix if you know how, or someplace that can.  Along with the buzzing from playing a cassette, the audio just seems a bit low.  However, the cassette player appears to be fully functioning aside from the fixable "buzz".  

All other functions work as well, along with all the original accessories.  

Soon, I will post the eBay link with a more detailed description, quality photos, and a video of this amazing vintage cassette player in-use. 

Feel free to message me with any interest or questions.

Just to let you know, I have sent you a message because I've been looking for that unit for some time.  I have the other HS-JX units, but that one has been the hardest for me to find.  I do know someone who can give it a tune up, so hopefully you'll let me know what your offer is on that.

Thanks for your inquiry!  I had thought about listing the JX303 for auction starting at $99.00 and let bidders determine the final price...or for someone who wants it bad enough, the "Buy It Now" option of $175.00
