I recently picked up a Beocenter 9500 off of eBay, and it actually made it to me in good shape! I was also glad that it came with the original box. This thread will be the progress I make (or struggle with) while bringing this beautiful Beocenter back to full life.

So far I have all the old adhesive from the glass and plastic brackets removed, and I'm applying 3M VHB tape to hold the glass in place.

The Beocenter powers on, tuner works for sure, and the powerlink sockets work for sure. I will have to get new belts for the CD and Cassette doors, a new belt for the Cassette mechanism, and probably a capacitor kit for the CD player.

Feel free to follow along and any advice you'd like to give would be appreciated. Thanks!

I have the glass all fixed up now. The touch sensors all seem to be working just fine. So that's good.

I then spent part of my day opening up the Beocenter. After opening it up, I found the CD player and Tape doors have a pulley system, and the CD player door is really messed up. Tape door has some issues too, so I'll have to look closer into that.

Great work - a BC9500 is well worth restoring. I have never tried re-threading those door strings, but it is supposed to be quite tricky. There's some instructions in the service manual I think. Here's some photos showing mine if that helps! (click to enlarge)

Also, when I put the Beocenter all back together, it no longer seems to power on. I'm not sure if I tripped a fuse or something?

Hi Beitie,

Thank you for sharing your work. May I suggest that you add your pictures in the post by clicking in the little framed mountain, last button in the window where you type your message? Better than as attachement because they will show up in the thread bigger than the little preview of an attached picture.

Thank you.

So after looking at things closely, I felt that I had a good chance at fixing the cassette deck door. The string for the top side of the door is still fully working and stringed properly. The lower string is loose, but doesn't seem too far off from what it should be.

I could tell by looking at this that the knot was still good in the string. It's very hard to see with the eye, but when looking at the photo, it's clear as day. So I tried to put the knot into the slot in the sliding bracket.

Even after getting the knot into the correct spot, the string was still loose. So something else must be wrong with it yet.

Sadly this project isn't going well at all. After my last post I continued a few attempts at repairing the Beocenter, but with each attempt, things got worse, not better.

Today I took the Beocenter up to a friends and between the two of us we got very close, but ultimately got beat by the Beocenter.

I can see how the string is supposed to go around the longer rod, but the level of difficulty and mental anguish it is to put that together is just too much for me.

I took this picture of my Beocenter 9000. Here I can see how many times the string goes around the rod, what directions the string comes off of it, etc. But even with four hands, we just couldn't manage to get the strings of the 9500 in the correct spots. It's a really bad, sinking feeling.

So after a lot of frustration, I couldn't stop thinking about the Beocenter, and I came up with an idea where I started with the slider, and directed the string from there, maybe I could get it taken care of correctly.

I think I got it. Though I still have a ton of work to do, and might have to re-do one of these sliders. I'm posting a video on the method I used, and I totally welcome any other suggestions, or pointers telling me where I went wrong.

Very clear video. Quick question that I should have asked earlier - do you have the Service Manual? It is available to Silver/Gold members of the site.

The manual (page 7-5) does show the string routing - as far as I can see the only difference is that the manual shows three loops around the revolving drive rod (not two as you have done). Of course, any slack may be taken up by the spring arrangement for the pulley at the other end. The service manual is not very clear on how the string attaches to the slider, but you seems to have found the solution to that.
