I still own Bang & Olufsen Beosystem 10. http://www.beoworld.org/prod_details.asp?pid=861
It features a very slim aluminum chassis, lab proven acoustic tuning and enough amplification power to drive a set of full size home speakers.
In B&O tradition music from any source can be heard at a single touch, primary controls are readily available while secondary controls are hidden.
For the best possible cassette sound auto reverse is omitted. Instead, a single direction tape transport is used. Cue and review can be used while in play to hear gaps between tracks.
It has an amplifier setting for low gain sources such as a phonograph.
It has three clever mechanical FM presets.
It has both AC and DC power inputs, left and right channel RCA audio connectors and left and right B&O style external speaker outputs.
Cloth speaker grille design matches B&O speakers from the era. I have bookshelf and floor standing sets.
Cassette transport was rebuilt about ten years ago but it is mainly used in connection with my iPhone (like almost all new B&O products are today).
