Slow response times from the Beogram’s control panel buttons pointed to potential oxidation on the keypad contacts. This was confirmed upon opening the keypad assembly, revealing dull key contacts.

The contact pads were unsoldered and removed for a closer look. While they seemed okay, the leaf contacts engaged by the actuators showed signs of oxidation.

To address the oxidation, a fiberglass brush and Deoxit were used, restoring the contacts to a shiny and clean condition.

The next electrical task involved replacing the RPM indicator lamps. This was crucial as LED replacements had proven to improve platter motor stability during testing. It’s important to note that the RPM indicator lamps are integral to the platter motor’s control circuit, and each speed indicator has a dedicated pitch (speed) adjustment knob.

Pictured below is the RPM indicator module with its original incandescent lamps.

And here’s the RPM indicator with the Beolover lamp replacement modules installed.

These Beolover modules are designed for compatibility with the pitch control circuit. Their SMD LEDs are calibrated to blend light colors, mimicking the original incandescent lamps.

The images below showcase the 33 and 45 RPM speeds illuminated by the new light modules. All control panel buttons now exhibit immediate responsiveness upon pressing.

With all Beogram functions now operational, the next stage involves meticulous checking and adjustment in line with the service manual’s guidelines. Once these adjustments are finalized and all checks are successfully passed, it will be time to enjoy the pleasure of vinyl playback once more.
