hello beogram fans,

when disassembling a Beogram 3000 5903, I discovered a previously unknown circuit modification.

The change is a supplement with 4 components, (transistor, diode and 2 resistors) Is this an official change from B & O or was someone very creative?

The change is located in the servo control of the tonearm.

I do not know what meaning or reason for this change
