Thanks, I see... But what's the knurled knob supposed to do when rotated?

It lifts or lowers the reproducer and horn and engages or disengages the feedscrew.

Aha, thanks! I didn't notice at first that this is the main control in these machines... I supposed they also had the front handle etc. Until I've seen a complete image of the motorboard of the B80!
