This was a mass manufactured in China, and aimed at the budget end of the market. However, it produces clear sound, and has qualities similar to the earlier Sanyo cassette players. A brand new one with box and original headphones could be around ten pounds or more.

It has some interesting electronic design features not available in other cassette players, and you can see some of them in the following pages of this multi-page article.
