Beogram 4002 Type 5513: Inside Work

My work on restoring a Beogram 4002 turntable from Houston continues, focusing on the internal components this time. This update covers the refurbishment of the tangential arm assembly and the replacement of the Beogram’s reservoir capacitor.

Here’s a current picture of the Beogram 4002 with its chassis and tangential arm assembly removed.

The tangential arm assembly components on this Beogram 4002 are in great condition. My work mainly involved cleaning and lubricating the Beogram chassis parts. The picture above shows the arm lowering damper taken apart. The parts themselves were clean, but the damper fluid was gone. I applied a new layer of PMX-200 silicone fluid, as per the service manual. Additionally, I cleaned and lubricated the tangential drive spindle and its nylon drive nut. All the tangential arm assembly tracking components were inspected and found to be in excellent condition.

I replaced two components: the tangential arm assembly position sensor lamp and the tangential drive pulley.

The old plastic pulley was swapped out for a new aluminum one.

Here’s a less commonly seen view of the underside of the Beogram 4002 tangential arm assembly carriage. It’s important to check this area during restoration. The fine wires from the phono cartridge run from the tonearm pivot base to a transfer board. A larger, shielded cable then carries the audio signals to the audio muting circuit right before they leave the Beogram and head to a preamplifier.

Lastly, here’s an image showcasing the newly installed Beogram 4002 reservoir capacitors. I opted for the high-quality Beolover replacement capacitor assembly, as is my standard practice.

This Beogram 4002 turntable restoration has been straightforward so far. These components are now ready to be reinstalled in the Beogram cabinet.
