Beogram 8000/8002: Replacement Part for the 'Knob' That Locks the 'Black Plate Under the Arms' in Place

The Beogram 8000 that I recently restored had a broken knob that locks the black plate under the arms in place. Its locking lever had broken off:

The broken part is shown on the left, together with an intact part on the right. I never really liked the design of this knob. It always seemed a bit of an afterthought, the way it slides into the plate, and considering how difficult it can be to turn it at times when it gets stuck. The usually damaged screwdriver slot is a testament to these issues:

So I was motivated to design a replacement that is a bit more functional. What I came up with is a two-component solution bolted together with a black M3x6 hex head screw countered by a square nut:

This part is now available at the DKaudiolover store.

Installation is straightforward: Insert the lower part into the orifice of the plate:

And then install the top part with the bolt:

Make sure the alignment features of the top and bottom parts catch before the bolt is tightened. This shows the installed part from the bottom, revealing the square nut in its recess:

After installation, the knob can be turned with a 2.5 mm hex driver. The integrated position indicator makes it easy to lock the plate properly after installing it:
