I took my BeoGram 1000 out of storage to check how my platter gets disassembled.

With my BeoGram 1000 it’s a 2 step:

1. Remove the C-clip to remove the inner (plastic) plate with the strobe markings.
2. Remove 3 screws on the main plate, to lift it from it’s holder (see the 2 pictures).

In your case, the 3 screws are rivets. So lifting the platter won’t work the way it does for me.

Though:

• If you need to check the suspension, the platter doesn’t have to be removed. For suspension you need to get the acces via the bottom of the plinth.
• If you need to replace the driving belt, there are ways (not the easiest ones) to do that with the platter in its normal position (for instance as described here after point 11)
• If you need to get the platter out of its way: since it seems to be attached to an assembly including the platter axes, there should be a way to release this axes from the shaft. But this can only be done from the bottom side.

Are you able to rotate the platter, or is it stuck?

For your information, the platter you are trying to remove, looks like this from the bottom side:

If I remember well, you should be able to lift the platter up/out.

I had the same the first time. But look very closely.

There is a C-clip that sits on the axel-pin in the middle (seen from the top). Remove that, but be careful that it doesn’t jump away.

When removed, you can lift the inner disc with the strobe markings.

Interestingly, the item on eBay mentions ‘VAM1250/21′ and the main picture shows the exact same box (and VAM1250’ on the white sticker on the box) as the unit I got from Keith Saunders.

If I would have to get one now, I would try this.

Very sorry to hear the VAM1254 does not work.

Though, even if they look almost the same, they are not. I read a lot of info about OPU’s. The VAM1250/21 that you need belongs to the ‘CDM-12 Pro’ family of OPU’s. Others are: VAM1204, VAM1205, VAM1206, VAM1252 and VAM1254. They all share comparable specifications, which also means there are differences. Unfortunately, you just found out about that.

The OPU you have in your BeoSound is a VAM1250/21, like I had. I was lucky to find one with the help of Keith Saunders. Although it is a VAM1250 (not /21), I know this one works.

You can try to contact Keith, but if I remember weel, he sent his last unit to me.

I made a quick check on eBay and found this one: https://www.ebay.com/itm/363230316872

It is a VAM1250, but I don’t know how reliable the advertisement/advertiser is. Maybe you can try to contact them.

Thanks for adding the picture. It confirms that your laser unit (in the MK2) is exactly the same, as mine (in a MK3).

This type is a little bit hard to find. I made a picture of the packaging on my replacement laser unit (see below). It does not contain any manufacturer/supplier specific text unfortunately. ( The Chinese characters mean ‘Chinese New Year’s Eve) And the barcode number is not leading to specific and right product or manufacturer information.

Though, the looks of the packaging might help you to find the right laser unit.

Hi Igor,

Can you share a picture of the sticker you refer to?

Fortunately, I was able to find a VAM 1250 through one of our respected members in the BeoWorld community: Keith Saunders (many thanks to him).

Also I got the laser unit with original packaging. And I think I remember that packaging from a Chinese manufacturers webshop page.
When I have time I will go check that again, because I guess there will be more people in need of this type of laser unit.

Best regards,

In the meantime I did find a VAM1250 at Dõnberg Electronics in Ireland:

https://www.donberg.co.uk/catalogue/vam_1250.html

But it doesn’t have the addition ‘/21’. So, I am not sure if this is the right one (Dönberg also doesn’t know if it will work.

 

Question

1. Does anyone know if this VAM1250 will work in the BeoSound 9000 MK3?
2. Are there any other laser units that are compatible with the VAM1250/21?

Thanks @B&O Orlando

I did find out in the meantime that the replacement for the BS9000 MKIII, is a VAM1255.
But also I found out that there are not that many available. Some form the US (too far/long shipping time cost) and some in Europe. In the end I ordered at http://www.DKSoundParts.com. They had the right one and reasonable pricing and shipping cost.

 

Curiosity / question

For getting to the sticker on the CD module. Can you give me some direction what should be disassembled?
Can you point put with these pictures?

Dear M.

Thanks so much for your extensive reply; very helpful suggestions!

The good news is that I solved getting the hinge screw loosened!

When taking another and closer look with a magnifier, I got the impression that it wasn’t a Torx screw. So, I just tried an allen key wrench on it, and immediately felt it made a perfect fit with good grip. So, I concluded it wasn’t a Torx screw but an allen key screw.

It was still very much stuck, but I was able to loosen it that much to get the glass panel out!

So this part is solved, thanks for all the help and suggestions: @Matador & @B&O Orlando

By the way, I checked with the owner. He bought the BS9000 brand new, and gad no service or repair on it. So it remains a mystery to have two different screws in the hinges.

 

Laser unit for BS9000

Thanks for the advice. I will first get the existing laser unit out and check which type it is. And then look at your tips for sourcing possibilities .

Good point M,

I have been very careful with using the soldering iron, and therefore I am sure nothing has melted.
My main focus has been on trying to get the ‘WD-40 anti corrosion lock lubricant’ to pull in. But with no result so far.

Question

Again, if this doesn’t work, I might have to drill the Torx-screw out, but then also replace the hinge (part) in which it sits.
But:

1. Is this a possibility?
2. Is the hinge part available?
3. About the CD Laser Pickup: the Service Manual mentions ‘CD VAM 1250 from serial no. 15143261’. So this means I need a VAM 1250 for this BeoSound 9000 MK3?

Thanks @B&O Orlando

I think you are right about the color. I took another look and compared the Torx screws from both hinges. The right/upper one (the losse one) is certainly black, and the left/lower one looks grey. So like you said, probably not original.

     

I have let the ‘WD-40 anti corrosion lock lubricant’ do its work overnight, but unfortunately still no movement.
Hopefully I can get a Torx-8 screw driver with a T-handgrip, to get a bit more force. But like you said, it is tricky.

But that is possibly because the ML connector on the BeoLab 3500 has to be activated by the Beo remote, to pick up the audio signal.

Hi Frog,

I am not sure if I understand your question correctly. But if you want to stream with a Chromecast through a BeoLab 3500, it is possible.

If this is what you want … I do this via the DIN-connector and a Mini-Jack-to-DIN cable. In this case you need a cable that connects the right way to the pins in the DIN-connector.

Then you have to use the Beo remote to activate the ML on the BeoLab 3500, and streaming works.

Let me know, if this is what you meant.
