tamtapir: The plastic cd clamper for Beocenter 9000? I buy one! Or seven. /***
I would love to, but I only have one working clamp, positioned in a BC 9000 and I dare not detach it.
It is probably the simplest and cheapest piece which done to most B & O-stuff ended up in electronics recycling.

I always find myself in the most unroutine restorations with B&O.
On the Workbench forum, any ideas on my topic "CD5500 CDM2 to CDM4 conversion"?

Collecting Vintage B&O is not a hobby, its a lifestyle.
Now you strap it onto the roof of your car, and take it through the car wash.
Oh, and don't forget to ask for the special wax spray!
Guaranteed to sparkle!
sparkling now!
It's always a relief when it still works once reassembled - I wonder if my wife will notice how beautifully the CD door opens now!

She will notice how good it looks, she will never notice how good the CD door works, but she will ask you to do the same with her kitchen appliances

This one's for Jacques!
He sourced some BeoGram 4000 parts for me in France, and sent them to me - Keyboard PCB, AC motor, and other bits.
Just like Frede likes to say about the BG4000's, this was a real troublemaker. 4 days of solid troubleshooting, and that was after the full restoration - new caps, resoldering all joints, a thorough cleaning.
Now the project's complete.
Right Click, Save As .. to watch some vintage eye candy
Hi,
Good job Menahem!
I often use this LP myself when testing Thanks for the video!
Another Beogram saved.

Finally I've had some progress on this project. It's been on my bench for months. Now it's more or less finished.
You guessed it! It's my IR receiver for the BM1900. It receives BL1000 codes and switches source and changes volume.
I decided to also add some sensing so that the uC can check which source is currently active. That way I can step through FM presets while still keeping the uC totally state-free.
The binding posts are for connecting an MCL2 transceiver. I decided to go with that because there is just no good place to put a TSOP7000 in this unit. Also, the way I plan to mount the BM it's better to put the IR receiver on the adjacent wall.
I had pretty strict real estate restrictions to be able to fit it in the space of the BM2400 remote receiver, but with a little thinking ahead it slides in beautifully.
Now I just need to add a connector and write some code to make this BM a link room unit. Then it will replace my BL2000 (which is neither pretty nor well sounding in my opinion) in the kitchen.

Great work!
Good idea that sense system. In my STB controller, I had to wire the uC to the power LED of the STB. Otherwise it was impossible to turn it on/off properly because of the annoying toggle type standby / power on command that most 3rd party devices have.

Yeah, I had that same problem with my TV, a Samsung, that I also built a BL1000 receiver for. I used the usb port on the tv, which is only on when the TV is on, for sensing. Although, I am using the discrete codes for on and off on the TV, but if you use the original remote or the the TV set itself, then you're toast.
The sensing in the BM is simply wire from the outputs of IC5 and IC6 (which turn on the lights) with a voltage divider to get a reasonable voltage. Works a treat.
Bad day at Elnas
In one receiver every and each one of these 10/25 were more or less popped, all other values were not.
blah-blah and photographs as needed
Do anyone know what is this bass element in S55? It doesnt look exactly like "high-end"
Among 10,000 other projects I have managed to dig up my reproduction BeoVox 2500. This time they are going to be passive and I just finished the second filter pcb. Getting soldered up today! Details to follow.
Beo4 'til I die!

I didn't know anyone else on here listened to Medina!
No one else has realised that Danish audio is designed for Danish artists ... simples!
Spent last night buttoning up the final touches to the new passive external crossovers for my reproduction BV2500s.
All I have to say is WOW.
Finally I finished my variac.
//Bo.A long list...

I'm currently working on my bachelor thesis... But it's not as funny as repairing or refurbing electronic stuff.
Søren Mexico:no bypass ??
No bypass! I did't think of that, but I'm planning to introduce a switch and a row of lamp holders so you can change lamp wattage by the switch.

Good idea, can you still buy lamps in Sweden, here in Mexico I have to search for them.

It's getting harder, but you can still find clear glass halogen lamps.
I need to make some room now to get this Beocenter 9300 into good shape. I was fortunate (I think) to find this locally for practically nothing. The unit seems to work except for the CD player. The cassette and radio work. The doors open and close smoothly without any problems. On the CD, the disk makes a racket when it tries to play so I am guessing the mechanism that holds it in place may not be engaging. Hopefully that is just a mechanical fix. I really should start in on the Beomaster 8000 waiting in line but if this is a quicker fix I might let it cut in line. Cosmetically it isn't in too bad a shape. There are a few small scratches and the rear grill covering the hookup area has a small broken piece out of the plastic.

It looks like the CD clamper is not moving into position to handle the disk.
Possibly the CD module is dislocated during transport (it sits on some springs). You'll need to open the top (watch out for the glass panels falling!).
Then you can load a CD manually by carefully moving the tip that is normally operated by the groove in the lid. If it plays fine, then make sure the module is correctly in place and put the top back on making sure that the mechanism engages the lid properly.
After the top cover is in place, and the CD door closed, you can adjust the lateral position of the CD, by 2 screws underneath the CD on the bottom metal chassis.
Place the BC9300 on a table, with the CD portion protruding over the table edge, and then you can reach underneath.
Loosen the screws only, do NOT remove them!
This Beocenter is missing some of the trim pieces for the glass panels (and they were already loose). So I removed them for now and found a source for some replacement trim pieces. With the glass panels out of the way I removed the screws for the lid and opened it up. Now that the lid is up, the CD clamper is in place. In this position I should be okay to operate the CD and test it out?
I now see what the problem most likely is...
Someone attempted to repair this unit previously. Looking under the CD lid you can see some sloppy glue attempt. Obviously the positioning of those plastic tracks are critical. Are those normally adjustable or were they originally molded to the lid and likely broke off? Any suggestions for repair other than find a replacement lid?
My mistake. That is just white grease. With the unit opened up I am able to play a CD now. However, I have to gently press down on the clamper as the CD spins up or there is a vibration that stops it from starting.
Here is a picture of the CD player working. The problem appears to be with the clamper arm assembly. If I leave it to try and start playing or stop playing without applying a small amount of pressure on the arm, the assembly jerks a little and makes a racket. Once playing though, it seems to work fine.
Playing with it some more it looks like there just isn't enough down pressure by the clamper arm to handle the start up and stopping actions.
I have a little bit of success now. Partially removing the CD transport, I adjusted the three clamper arm screws and am able to get the CD to start and stop without having to manually help it. I need to play some more with adjustments though as there is some skipping in the CD while it plays.
I fine tuned the adjustments on the three screws and now the Beocenter CD player is playing correctly (without any assistance from my finger ).Now I just need the plastic trim pieces for the two glass panels to arrive and I can start seeing how I like this great looking piece of equipment. It is a little modern for what I usually go for. My favorite Bang & Olufsen receiver is still the Beomaster 4400 but I could resist picking up this newer unit. Plus the Beocenter has a CD player and a cassette deck.I have a big Yamaha power amplifier I need to try and get back working next. After that I am really hoping to be able to start on my Beomaster 8000. It has been staring at me for a few months now.

Have you listened to the cassette section yet?
Its so nice when you once in a while find equipment that is repairable with just a little adjustment and LTC
Working on a record cleaner, Rich pushed me, he want a motor driven cleaner, I gave it some thoughts, but decided on a manual with protection for labels.
Here the beginning of a prototype, the cleaning pads are made of a 3M cleaning pad (spongy) covered with microfiber cloth. Today I´m going to make the shaft with covers for labels.
