There are bargains to be had. A friend bought a working Beogram 4000 with good MMC20CL for £20. But not on eBay!

A perfectly reasonable suggestion but why complicate things? I would use the Beocenter 7700 and S45-2 speakers but I would attach a second record player to the 7700 Aux input via a decent variable RIAA which would give line output. I would also get a Beogram 1000 rather than the model you mention. It will cost much less but will play 78rpm records,

I would guess one of the buttons may be sticking on. I would completely take it apart and clean it.

A little mean I think. The 9000 is relatively rare and is a very complex tape recorder with excellent performance. I would suggest that a perfect one could easily reach £150 and more if boxed. Extra value adding accessories would include the azimuth aligning tape and tape head cleaning set as well as the original manuals.

How are you loading the music? I seem to remember that when playing with this device, one needed to load the files into a sub file first.

Unfortunately not. B&O threw away all the trim items for this era of product some years ago. Your choices are limited to finding a donor unit or repairing what you have. Someone may have a donor unit on site.

Check the connections. If using a DIN plug, the wires may be loose inside. There is a muting circuit so I suppose that this might be faulty but I would suspect the connections first.

Sounds like it needs new belts. Very common problem. Martin (Dillen on site) can supply new ones.

Not completely sure what the problem is but I will guess. The first Beocom 2s had their own base and did not work with a normal Beoline. They can however be modified to do so but you will need to see your dealer to get this done. It requires new hardware in the phone.

Sounds like you need some new batteries. I would check the contacts on the phone for corrosion first if they have not been used for a while. Otherwise, just replace the batteries. They seem not to tricky to find - I did a quick search and immediately found this .
