1956 Beocord Unitape 512 K
Back to gallerySpecifications


Many thanks to Get Reel's Danish correspondent, Flemming Sorensen for the information on this page.

In the mid 50's, audio equipment was still rather expensive so B&O came up with a quite innovative idea in 1956. By combining amplifier, tape recorder, and record player in a single unit, you could save some
money.

The result was this rather awkward looking machine which I believe sold quite well. I have seen it a couple of times at antique sales but they are rather expensive nowadays.


An old technician I once spoke to told me that it was rather a popular piece of equipment in dancing schools because of its ability to do variospeed. When rehearsing the dance for the first time the music could be slowed down and then put to the correct speed when the dancers had gotten the steps right.

Last time I saw one I tried to lift it. I had to use both hands so I guess it weighs more than 15kg. Like the beocord 507 it can be used on both AC and DC voltage.
