Take out the metal bar (two screws).
Insert from one end, rotate and slide further, rotate again and slide etc.

Surely not as good as if the original woofers were kept and refoamed.
I seem to remember the original woofers being 16 ohms impedance – they certainly are in parallel for 8 Ohms speaker impedance.

Vas 89.1 l

This alone says no.
I have never seen anything coming close to the original.

Put a record on the platter and press play.

Sorry, couldn’t help it, but I get emails from frustrated owners of newer digital and app-controlled stuff almost daily, and there’s
absolutely no way for me to help them other than suggest moving away from all the unnecessary technical nonsense, that should
work but for some reason doesn’t.
Back to basics.

Not that easy to say, as f.e. Beogram 1000 was made with several different motor types.

You can find new motor bearings etc. at Danish Sound Parts. What other internals do you need?

Martin

[Dillen]

It’s a press-fit.
Just pull it off, and try not to distort it, so pull close to the spindle.

Did you use the right brand and type of capacitor for C2103?
Not any old capacitor will work here, as we have discussed previously on these pages.

Martin

[Dillen]

Replace the small capacitors in the regulator circuits.
3x 10uF and 1x 22uF if I remember correctly.

Martin

[Dillen]

Mystery solved.
It’s not a B&O part.

Actually, it was recognized as a foot for a vintage cassette tape carousel.  🤓

Take out the battery again.
Leave it overnight.
Fit the battery and try again.

Martin

[Dillen]

They are identical.

Martin

[Dillen]

It looks the same on the other side.
Bottom is plain and black, apprx 20x65mm.

Martin

[Dillen]

Bad adjustment of the interrupter and/or bad LDR resistor.

Martin

Note that Beomaster 4400 was produced with two different types of potentiometers.
They have different mounting and are not interchangable.
The early type is the same as Beomaster 3000/4000.

Martin

[Dillen]

So the Beomaster does not send back to the remote.
Or the remote cannot receive.

Martin

[Dillen]

Check the idle currents!
The trimmers will be bad – just as bad as the capacitors you’ve noticed, and they will need replacing and realigning.
Did it smoke – check/replace the emitter resistors as well.
A convenient service kit is available containing caps and trimmers.

Martin

I have seen both left and right aligned models.
Definitely most left.
It’s not that at some point mirrored pairs were sold. No, they are always found in pairs, either both left or both right.
Why, I cannot say.

Martin

[Dillen]

Don’t increase the wattage of the resistors.
Some of them double as “overload fuses” to protect the drivers.
If the resistors are not burned or physically damaged, I would leave them well alone. They will be fine.

47uF or 50uF (depending on OEM) doesn’t matter much, seeing as the tolerances of the original caps
were typically +/- 20%, and you can find them fitted randomly from factory.

Martin

[Dillen]

It’s not difficult to find a woofer that will fit physically.
Finding one with the same T/S parameters, on the other hand, is impossible. (Keep in mind this is in effect a woofer in a midrange size).
The original woofer was custom produced for this speaker. A similar looking one was used in a larger Beovox model, but they
are far from identical parameter-wise.
I would repair the original woofers. Perhaps you can do it yourself. There are threads here in the forum showing how
to do the S45 woofer, which suffer from the same issue.
Same goes for the speaker used in the slim 1970s Beolit portable radios.

Martin

All Beovox 2700 and 2702 use foam.
