Following the replacement of the damaged MMC cartridge mount in the Beogram 4000 restoration, the next step was to switch out the last incandescent bulb with an LED replacement. The image displays the bulb housing removed from the sensor arm.

The underside of the small PCB and its wiring are shown here:

Constructed on a flexible printed circuit board, the LED module is designed to mimic the energy consumption of the original light bulb, preventing any issues with the Beogram’s control system (which verifies if the bulb is working).

The bulb was then removed. The photo compares the original bulb with the folded, flexible printed circuit board LED assembly designed for direct replacement.

For other B&O enthusiasts, this assembly is available. Reach out through email or the contact form provided for details. This image showcases the installed LED assembly:

And here it is in operation:

A small, 3D-printed red wedge placed atop the PCB ensures the LED is positioned to correctly project light through the lens at the base of the bulb compartment.
