Bit of an odd head-scratcher here. I have a Beocenter 1800 that is working fine except for the fact that I cannot get the arm on the turntable to zero-balance.

When I acquired it, the spring and the retaining screw for the counterweight were missing so I sourced and fitted these but, even with the screw winding the weight fully to the rear, the arm is still too ‘nose-heavy’ and I cannot reduce the tracking force to anywhere near what it should be.

Any ideas? Does the arm have the wrong counterweight (anyone know how much it should weigh?). Is there an auxiliary weight hidden anywhere that I’m not aware of?

Any thoughts gratefully received.

Hi Adam

Maybe there is a 2nd counterweight missing.

If you look on page 4.3 in the SM Beogram 3400-1900-1100 there are two of them.

1 the one you mentioned Part Nr 52 Counterweight

2 that maybe missing Part Nr 63 Counterweight

seems it is connected to Part Nr 60 pointer ( slider)

Kind regards

Ah, now that’s interesting – thanks; I hadn’t spotted that!

I shall investigate…

And there are in fact two different counterweights – used in different models, but very similarly looking and not interchangeable.

I think that may be my problem. The second weight under the arm is present and correct, but I notice in all the pictures, the counterweight cover on the Beocenter 1800 arm is silver but mine is black.

I’m guessing I have the wrong weight and it’s too light?
