It was time for the final adjustments on the Beogram 4002 (5514) restoration project. Adjusting the platter and sub-chassis, arm lowering limits, and tracking force is always a satisfying part of the process. It means the turntable is ready for its initial post-restoration playback. Observing the intricate mechanics in motion, bringing out the best in vintage vinyl, is always captivating.

This Beogram presented a unique sub-chassis and platter adjustment challenge. The platter was positioned too close to the front right edge of the aluminum plate cutout. Typically, the platter sits too close to the motor, rectified by adjusting the sub-chassis spring rod on the back right. However, this situation demanded a different approach: increasing the counter-force on the left back spring. Instead of using the service manual’s rod-bending method, a more elegant solution was devised. Using large pliers to bend delicate rods on such equipment lacks precision and reversibility.

The solution involved designing small, 3D-printed components that attach to the blade springs. These allow for lateral adjustment of the metal strings suspending the sub-chassis.

Here, one is shown in use on the left-back spring assembly:

The integrated ramp on the bottom section gently pulls the string backward, applying the precise counter-force needed for platter centering:

Videos detailing the procedures for platter bearing adjustment and sub-chassis adjustment (on a Beogram 4000) can be found on my YouTube channel. The process is quite similar for the 4002. Next came the tracking and arm adjustments. The image below demonstrates the tracking sensor sensitivity adjustment using the light intensity trimmer on my LED-based tracking sensor:

This presented a chance to introduce a recent acquisition and new least favorite: Henry Mancini’s ‘Gaily, Gaily’ movie score. Purchased as a $1.50 add-on for combined shipping, it was a regretful impulse buy. While generally a Mancini fan, this record proved to be excessive. However, it’s perfect for the tracking sensor adjustment, which can lead to the needle dragging across the record if not handled carefully.

Next was the arm lowering limit adjustment:

This important adjustment prevents the stylus from contacting the platter ribs if the sensor malfunctions. A video illustrating lowering limit adjustment is available on my YouTube channel. With the arm adjusted, tracking force can be calibrated, typically using a B&O tracking force gauge:

A video on tracking force calibration is also available.

Finally, it was time to test the turntable. The chosen record was ‘El Chico,’ a 1965 release by Chico Hamilton:

An early Impulse pressing was acquired, as covers without barcodes are preferable.

Disappointingly, the record wasn’t “near-mint” as advertised, but rather “very good” with audible scratches. Thankfully, the eBay seller issued a full refund, allowing me to keep the vinyl. After a thorough cleaning with a CleanerVinyl ultrasonic cleaner attachment, the record is enjoyable, though the scratches seem to accentuate its raw emotional power. This music exemplifies the allure of analog audio. “People” on side A, featuring guitarist Gabor Szabo at his best, is a standout track:

The final touch is polishing the hood of this Beogram 4002 before its journey home. This is Beolove!
