There are two Beomaster 1700's.
One is a tuner only, meant for use with the Beolab 1700 amplifier, both in the front operated stacking design.
The other is a complete receiver with tuner and amplifier, operated on the sloping top with the two caterpillar bands.
The latter is in my opinion one of the most beautiful and extraordinary designs from Jacob Jensen.
Glass and anodized aluminum. A classic really and definitely one of my design favourites.
Performance may not be that special but it has a fairly good reception and a pleasant sound.
The caterpillar bands tend to slip and the same goes for the button-operated clutches they drive. Usually fixable though and at some point B&O realized the problems and even made a kit to correct it (sadly no longer available).
