Nice system, Dennis. I’ve never seen a Beogram 5005 with a Beogram 3000 lid (with the buttons). Nor was I aware of the BM4000/BC4000. Thanks for sharing.
They are pre-production units.
I have an earlier version of the Beogram 5005 with the orange lettering and sloping dustcover. Mine is more "rough" and f.e. has unpolished and
unlettered deck buttons.
