Hi Yann

Please contact me at yachadm AT gmail DOT com

I have all the necessary components you need to supply your tech, to repair your circuit boards to new operating specifications.

Hello!

Thanks to both of you.

Sure that my dealer's tech will be able to change the dead components... The tricky part will be to find the missing spare parts!

Kind regards,

Yann.

Hello Yann,

I don't own a 9000 (although I'd like to...) but I can imagine lookin' at the SM:

mute - that one has been answered - relay.

memory: There's a small battery in the unit, will have to be replaced. Not a standard cell though.

tape: probably a belt problem with the rotation detector - surely Martin (Dillen) will fall in here.

CD: most likely a capacitor problem. There are specialists for CD here.

A good technician should be able to do this on a component level - but most shops are used to board changing only nowadays

Good luck,

Gunther

The first problem is probably a faulty mute relay - very common on BC9000/9500 and replacements readily available and cheap (no need to buy the B&O replacement!). I changed mine myself but any technician will be able to replace when he is fixing the other faults.

Sorry but I can't help with the other probs. Good luck!

Hello!

After one year of rest in their original boxes due to a move, I brought back to live my 1987 Beocenter 9000 and 1984 Beogram 6006.

The Beocenter has unfortunately several faults and a strange behaviour when playing CDs. It was OK before it's "hibernation".

- No more sound on the main outputs, but the other ones are OK --> The amplifiers seems to be OK but no more "mute" function and I do not hear the relay clipping when touching the "mute" button.

- No more memory. As soon as I unplug it, the Beocenter looses the time and I have to input the time when re-plugging (before, time was held for a few moments).

- The Wind/Rewind function of the tape player do not work. If I touch the "record" button, the level display works for a few seconds, then disappear.

- The CD player refuses to play SOME CDs. The disc spins for a while, then the player stops.

I found the following workaround (it works for 75% of CDs):

1: I put one CD in the player (always the same Nina Simone CD which always plays without problem).

2: I stop the CD, then change it for the one I first intended to play and was "refused" by the player... and it works.

I hope my beloved BC9000 is not dead, since the CD player seams to be able to read some CDs.

Is it the "capacitors" syndrom?

I have no ability to repair the BC by myself, but I have a good dealer who might be able to do.

When I explained the problem to the tech, he told me that CD units are no more available (a thing that I know), but I refuse to let my BC die without trying to do something.

Some of you seem to repair vintage units and havesets of belts, capacitors and other spare parts. Are they still available?

In one word:

HELP !!!!! [:'(]

Thanks by advance for any diagnostic, advise or help to get spare parts.

Yann.
