Beogram 4002 (5513): Second Unit From Houston

A few weeks back, I completed the first of two Beogram 4002 (Type 5513) turntable restorations for a client in Houston. I’m now starting work on the second one. Both turntable platters had their motors removed before being sent to Beolover for refurbishment. He has since finished these and documented the process on his blog.

I believe that refurbishing the platter motor is an essential step in any Beogram 400x restoration project. Neglecting this would be similar to never changing the oil in a car. It’s crucial to prioritize this before tackling the electrical restoration of the Beogram’s main board. Beolover’s motor restoration service includes rigorous speed stability tests, which involve determining the correct capacitance value for the main board’s 1C10 capacitor.

Pictured below is the second Beogram 4002 (5513) unit, opened up. The empty space in the lower left corner of the cabinet is where the platter motor was originally mounted.

This unit, like the first, exhibited a significant amount of oil within the chassis. My initial step involves disassembling the Beogram for inspection and cleaning, followed by the restoration of individual components.

This particular Beogram has undergone previous repairs. A new phono cable was installed, enabling the use of preamplifiers with RCA inputs instead of the standard B&O DIN plug. The cable itself seems to be in good condition and is fitted with high-quality RCA jacks. However, I’m not entirely satisfied with how the new cable connects to the Beogram’s output board. I might need to modify this connection to bring the cable closer to the board’s plug before proceeding with the separation of the shields.

The previous Beogram 4002 I restored for this owner had its transport lock bushings in excellent condition. Since they were still pliable, I opted not to replace them, applying only a minimal amount of plastic/rubber conditioner.

In contrast, the bushings in this unit have deteriorated considerably. They have become brittle and crumble easily even with the slightest touch.

To effectively remove the bushing debris, I have extracted the tonearm assembly from the main cabinet.

The excessive lubrication of the tangential drive screw has resulted in a substantial amount of oily residue within the Beogram’s cabinet. This oil is flung off the spinning drive screw during operation, coating the interior.

The tonearm assembly is also visibly affected by this oil contamination.

While the tonearm assembly requires further cleaning, the Beogram’s cabinet is now completely clean and ready for reassembly.

The next steps involve completing the tonearm assembly cleanup and conducting initial mechanical inspections and adjustments.
