three-speed domestic class quarter-track stereo recorder from Sweden which
came in two finishes. the model 423 in a teak cabinet (pictured here)
and the MP 424 in a portable carry case covered with plastic fabric and
fitted with a detachable strap.
The twin magic eye record level indicators were
strategically placed at the front edge of the deck in such a position
that they could be seen clearly from either a sitting or standing position.
Another clever innovation was the placement of all input and output sockets
behind a removable panel on the front of the cabinet making access to
these facilities extremely easy.
