My Beogram 4000 restoration is complete, and it’s playing beautifully. As I write this, I’m enjoying “Song for My Father” by Horace Silver on a reissue, as original pressings are unfortunately outside my budget these days.

One of the final tasks was refining the Beogram’s mechanics. I calibrated the tonearm weight and limits and replaced the guiding washer, which ensures the plinth moves smoothly. The original washer, pictured below, has a design flaw that was later corrected in the Beogram 400x series.

The updated eccentric washer design, which I replicated using 3D printing (see installation video here), is much more effective. These printed washers are available in my Shapeways store (five are needed for a full replacement). The new washer, along with a new M3 bolt, creates a lower profile, preventing the aluminum panels from rubbing during installation.

After this adjustment, I calibrated the tonearm, ensuring accurate tracking force and a secure lowering limit. This is crucial to protect the MMC cartridge needle in case of a faulty photosensor or bulb. I’ve previously posted videos about tracking force calibration and arm lowering limit adjustment.

Another important step was reinforcing the weight adjustment screw assembly. Replacing the original locking washer with an M3 nut and washer creates a more secure, permanent setting, which is essential for safe transport. This prevents calibration shifts during shipping.

Here’s the final result: the needle precisely calibrated to 1g on the tracking force gauge.

Listening to Horace Silver on a perfectly calibrated Beogram 4000 through my Beomaster 6000 4-Channel system is pure audio bliss.
