I have this one for about 4 years, never had problems with it. I don't use it too often and decided to sell. Playback sound is awesome with any prerecorded tapes, record sound is good too. 

All functions work as it should, all lights, including the inside cassette light works.

When I tested it few hours ago I noticed that the Headphones volume is noisy and Record volume same - but after I moved the sliders up and down few times was fine - so, it might need to be cleaned if you like.

Cosmetic condition: a bit dusty, need a good clean (please check photos). Some small marks on the top edge and few small scratches and marks on top cover (please see photos). 

Any questions, please do not hesitate to ask.
