I recently received a DC platter motor, the main PCB, and the RPM panel from a Beogram 4002 (5521) for restoration. The parts reached me via a personal courier from the Netherlands. As usual I started working on the motor first since it can take a few days until the motor bearings are infused with fresh oil. This shows the motor as received:

Beogram 4000: A Very Corroded New Arrival from Sweden
I recently received a Beogram 4000 from Sweden. It arrived double-boxed and there was no shipping damage. A good sign! I extracted it from the boxes and put it on the bench. This post summarizes my first impressions.
First the good: This Beogram 4000 came with pretty decent aluminum surfaces. The platter is in good condition. The lettering on the arms cover was protected and therefore survived. The big and small panels are also pretty good. But we will see after cleaning them how good they are. The unit is pretty dirty.

Beogram 4000: A Fun Evening with a Smoking Solenoid Resistor

After I plugged in and pressed ON, the unit started normally, but at the LP set-down point the arm would not lower. Instead the unit gave me a vivid demonstration of 'burnt smell', while a thin plume of smoke rapidly developed on the left side of the PCB that carries the carriage switches.
I quickly pulled the plug and lifted the PCB and found a browned solenoid resistor (7R1) and a blackened board:
