Hi Martin,
They were definitely not o-rings, but just bad quality belts, probably a little loose?
I wonder how such sellers (I contacted him before buying) can have such positive evaluations. 👍
You only have 60 days to leave feedback on Ebay. If the purchased item holds on for that long the seller is in the clear.
And did you say Portugal? Now, where did I hear about this before...? ❓
Beocord 2000
This one arrived with a note stating "Huge wow".
I tested it and had to agree. Huge wow indeed.
Near tape ends it could hardly pull the tape - but I could hear the motor run.
I opened up the Beocord and had a look inside. This is where it became clear to me, that this
was going to be one more belt story.
The capstan belt was huge. And not only was it huge, it was also quite stiff.
Actually, it was so stiff that it didn't hug the barrel shaped motor pulley correctly, - it merely
sat on the widest section of the pulley, completely flat, only touching the pulley along the center of the belt,
which over a period of about a year had worn completely shiny and smooth with no friction left whatsoever.
In this photo I think you can tell, that the belt doesn't touch the motor pulley at its sides, only at its center.
Laying it on a piece of cardboard the belt was so rigid I had to press it down with a finger to make it lay flat.
The other belt is the real thing, note how flexible and agile it is. Completely different.
The new belt was fitted.
Note how it embraces the pulley and adapts to its shape for full contact.
The other two belts got replaced too, and a couple of known troublemaker capacitors in the Dolby circuit was
attended to as well.
Fresh idler wheel and reel table rubber parts were fitted for good measure.
It played along for a couple of hours and back it went.

Where can I get repair kit for bm1900. I bought this in 1979 and has lain in my attic for the last 10 years. Now suffering from similar ailment that I've read about on this forum. Comes out of standby briefly and goes off again. Also a tutorial for carrying out repairs?
I am not aware of any tutorial as such. Repairing electronics is really a job for a trained tech guy or an experienced DIY'er, but some of
the kits come with (dis-)assembly instructions (photos and english text).
In your case I would check the solder joints at the large output stage transistors for cracks and if that's all fine check for presence of DC on an output.
Capacitor kit, lamp kit, potentiometer repairs kit - all available.
PM or email me.

Beogram 3000
The tangential version.
Owner told me it had a huge wow and my thoughts soon circled around platter belt and motor (I have seen to many wrong belts causing problems in these decks).
But I could not replicate the problem.
It just kept on playing without a single glitch, so I decided to give it a good cleaning, a dose of fresh
lubricants and a fresh set of belts for good measure.
Then test it again.
It played along and all was fine.. - until I closed the dustcover.
Then it suddenly - but certainly - produced wow!
The problem was soon diagnosed as a to high setting of the subchassis.
I must admit I didn't notice it at first, but the subchassis was set high enough to see the outer perimeter of a record on the
platter actually touching the inner side of the frontmost part of the sloping dustcover.
Admitted, it's not like there is a lot of room to spare in those quarters, but it shouldn't touch.
I did the adjustments and put it all back correctly and the deck was back in business.
I have a small notebook where I collect faults and solutions. It has proved to be an invaluable source of experience and information, particularly useful when people email me with all kinds of problems and symptoms - for their B&O units, that is.
This one was added.

This book clearly needs to be published!! Certainly would be fascinating to see - I know Tim used to put similar episodes on the Beocentral site. However a small publication run would be even better!

Today a little assistance was called in to help replacing old and flattened rubber feet.
The new feet are cast in neutral rubber to keep this lovely Beomaster 700K from leaving black footprints on furniture and shelves.
And after that more than a bit of cleaning...
Eek...Once a smokers, apparently.
We talked about how everything else in this persons home must have looked, smelled ... - and felt.

Good to see you are training the next generation of B&O technicians. This will ensure these vintage jewels will continue to work for decades more :-).
