This type of problem is common on the Beogram 4000 turntables (as they are the oldest in the series) but is not unheard of in the Beogram 4002 Type 5513. I ran into a faulty phono cartridge connector on a Beogram 4002 Type 5513 back in 2017.
This problem would be a huge problem for an owner and require stealing a good connector off another Beogram turntable if it weren't for Beolover having a replacement part for it.
I will use the Beolover replacement part to repair this Beogram 4002 turntable.
First off I need to prepare the Beogram for the new phono connector.
That means removing the tonearm by unscrewing the two mounting screws that attach it to the tonearm base assembly.
The aluminum tonearm tube pulls out to expose the phono wires and a small transfer board. The transfer board is where the color coded wires from the phono connector connect to the very thin wires that take the signal through the tonearm base.
I am using a small mirror in the two photos below to show the top and bottom sides of the wiring transfer board.
After desoldering the phono wires from the board the tonearm assembly can be removed.
I performed the usual boiling water to ice water trick to loosen the glue that holds the tonearm cartridge connector inside the aluminum tube. That let me push the connector out of the tube so it can be repaired.
Unfortunately I don't have the Beolover replacement phono connector in my stock of Beogram parts so I quickly ordered one.
In the meantime....continuing the repair preparation, I turned the tangential arm assembly over so I can easily get to the wiring board. When the replacement phono cartridge connector arrives I will install new phono wires from the new connector to the transfer board.
It shouldn't take long to reattach the wires and this Beogram will be ready to go again.
