I meant hard to find as Is it hard to find new ones online. I think I know where those fuses are, under a black plastic box close to the transformer, right?

I'll try as you said to move the selector back and forth, may be I add some contact cleaner and see. I was home this morning but now I get back to the office, so I won't be able to try before this evening.

And what do you think about the compatibility of that PSU type 5524 instead of 5521 ou 5525 ?

I believe they are the same. But methinks it won't come to that!

And nothing tells you that the new one will be better anyway...

OK, I changed the fuse I blew and doing so I discovered that instead of the two 125 mA fuses I was supposed to have, there was a 125mA and a 250mA. I replaced them by two 125mA just like it's written on the fusebox and on the diagram I found online.
Then I set the voltage selector on 240 just like Chartz told me and it still vibrate but I am not sure if I can do better even with another transformer… 

@Chartz, I believe you're in France and have a 4002, does yours vibrates a little bit too ?
When I went to the store where I bought the fuses, the guy said that if I could not set the voltage selector on 230v then the transformer would necessarily vibrate because of the difference between the voltage setting and the actual voltage that is close to 230v. 
So he proposed to change he transformer for a new one,I think I'll consider it 

No my transformer stopped vibrating after the switch over to 240V. It is completely silent.

What the bloke told you is rubbish. And he certainly won't be able to supply a B&O transformer, nor will he be able to find one with the same characteristics for that matter!

An old trick: halve two squash balls and use them as dampers under the beograms feet. Should dampen the buzzing enough. Most of the noise will be amplified noise from the table the beogram stands on. The platter etc are buzz isolated by springs so will not pick up the humming and send it to the amp and loudspeakers anyway.

I agree changing the transformer is doubtful as it will be the same transformer you already have...

Thanks, I'll try the squash ball trick and let you know but still L'll wait to see if I can buy another begrime transformer, I doubt that the squash would be enough and it's a pity not to be able to enjoy this great turnable.

Hi guys,
The vibration didn't stop but reduced, so I'll do with it et unplug the turntable each time I don't use it (if not it would drive me crazy). But now I have another thing going on, since I close the deck I had problems with the tonearm… you must think I am dumd and break everything, but I swear I have been very careful I really don't know where that comes from.

Here's what happened, when I first tried to listen a record since I changed the fuses, the tonearm didn't get down on the record low enough the cartridge barley touched the disc. So I checked the tracking force and it was set on 0,5g, and with the MMC20CL cartridge I have it should be about 1g, so I set it right (I though it was that way before but maybe it moved while I was opening the deck?).
Now the tonearm goes down right on the disc and plays it very well until a certain point. On every record I tried, at the same point, the tonearm stop going forward and the cartridge jumps just like the disc was broken, you know it jumps a sec backward, go forth and jumps again… 

Do you know where that can come from ?
