Have you recapped the servo PCB?

[chartz]

Hi,

And then news when the (easy) repair is done!

Best wishes,

Jacques

Hi Rune,

I’d leave it if there isn’t any oxydation inside. Also check whether some of it was burnt by overloaded resistors in the crossover, which could explain the bad smell as well.

You can otherwise use the same wool made of recycled clothes, available from shops that sell fabric.

[chartz]

No you can’t. The thump is normal.

Mine has done that every day for almost ten years. Many amps have a speaker switching relay to avoid it. To reduce it, you may try new power supply capacitors, but it will still be there.

If the problem magically disappeared it may come back, so beware.

Hi,

Also check the transistors in the output stages, especially drivers and pre drivers. They can be intermittent.

That Philips tweeter was very good. It was used in many great speakers, including Philips’s own legendary MFB active speakers. I agree that replacing the Xover caps should be tried, hoping that the units were not damaged.

No ferrofluid was used by Philips, by the way.

Hi,

What you describe seems normal to me, as said above, nothing special. All critical parts are readily available.
Every item will need standard maintenance, all worth it if they still look nice!

Good luck finding someone who can do it though. B&O won’t be able to help here I’m afraid.

Hi,

You’ll have to find original woofers I’m afraid.
Don’t forget that the speakers were designed around the chosen units.

Hi,

That remains expensive for such an old cartridge with a perished suspension, even if the tip is new.
Its real value is next to nothing and it was the basic cheapest cartridge in the range back when it was readily available anyway.
You are optimistic and the buyer might be bitterly disappointed. As our friend Matador said, we all know that here!

Hi,

Have you considered rubber shock absorbers? Those are available here : https://www.beoparts-shop.com/product/disc-drive-suspension-rubber-repair-kit-for-beogram-cd5500-cd6500-cd7000.

[chartz]

Well done Herrit!
Nice set I prefer using with MC-120 speakers.

Hi Lee and Keith,

The basic forum user could just be called Beoworld Member, and we could be called Active Member or Donator or something like that?

I think the archived forums should be opened to everyone though.

Yearly draw it is then, and perhaps the full access to manuals is enough. Perhaps something that would cost nothing, like a free manual download per month for every member?

Best wishes,

Jacques

Repro dust covers are readily available these days.

Mine is also museum mint, but is on display (and used) at home.

But £ 2,000 for a Beogram 4000 is still sheer madness.

[chartz]

I have the same system (BM5500 / CD5500/BG5005) and my Beo4 worked with it straight away.

[chartz]

I agree, this is pure folly. The times when you could get one as a nice restoration project for € 80 (what I paid for mine) are well over. These are not even rare, they were produced in large numbers.

Right now there’s a tatty 4000 platter and the seller wants £ 200 for it!

And another one wants € 14,000 for a restored 4000, not even mint ?

Should we blame B&O for that, with the recent release of their special 4002, rebadged as a 4000?

 

[chartz]

Whenever I want to use a turntable that has a DIN plug (B&O, Dual) I use an adaptor. Better than chopping the original DIN off, surely?

[chartz]

The head is probably intact. Only Bogen heads on open reel Beocords and Uhers pose problems.

Do check capacitors around the Dolby circuit.

[chartz]

I’d revert to the better DIN plug that has the correct grounding, separate from modulation.

What’s with those guys who systematically want RCA fitted to vintage equipment anyway? ?

The SP10 isn’t lighter than the SP6/7. An SP12 is nice but mine was new old stock and its suspension collapsed very quickly. So beware.

[chartz]

Hi,

Have you had a look at the service manual? I seem to remember everything is explained in it.

[chartz]

Yes it is glued, but it can be opened with some care. Not for the faint of heart though.
