I combined three units acquired through auctions, selecting only the best parts. The cassette deck underwent head demagnetization, head cleaning, leaf switch contact improvement, capstan belt replacement, and lubrication of the mechanical components. The original speakers were replaced with new 4-inch full-range speakers, as the old ones were likely to have poor sound quality. I believe the appearance has been improved. Please check the sound quality in the video. I have confirmed input sound output from AUX and PHONO, AM/FM reception, and tape playback, rewind, fast forward, and recording functionality. However, as this is a component from over 40 years ago, it is being sold as junk due to age-related deterioration. Battery operation has also been confirmed. The photos show everything. No returns or refunds, please. The price includes shipping. Here is the operational check video. The recording tape has been used many times, so the sound quality is poor. Please be aware of this. https://www.youtube.com/watch?v=3SBYIJVJXsc
