  • Beocenter 7700 "slider"/lid lift mechanism

    Hi everyone, I am trying to complete the restoration of a Beocenter 7700. Getting closer, but I have an issue I cannot figure out. I referred to this old post for guidance: https://archivedforum.beoworld.org/forums/t/34814.aspx ...where it describes how a tiny plastic "slider" is part of the mechanism used to lift the lid (See image below). I looked everywere inside, but no "slider" could be found lost inside the unit. It's really hard to figure out how the lid mechanism works

  • Beocenter 7700 lid lift mechanism

    Looked at the service manual, but I am completely baffled by how the programming lid lift mechanism works on the Beocenter 7700. Feeling discouraged. I just came across this post: https://archivedforum.beoworld.org/forums/t/34814.aspx For me, I have three pieces that don't seem to connect properly: 1) damper plate, the bow shaped plastic piece, which apparently mounts onto a little cylindrical protrustion on the chassis. 2) friction damper plate (aka "hinge piece"), looks like this

    I did take care to get that brake back into where it should be. The video that I watched really stressed the importance of doing this properly. However, I’ve taken the mechanism apart to have a look again. Here is what I noticed. I see three ‘brakes’ (see photo in the next post), one on the left and two on the right. None of them have brake pads, but I think they once did. I found two brake pads floating around (see photo) and maybe there’s a third one in there. I guess I

    Also, I just saw this thread: https://forum.beoworld.org/forums/p/2959/26546.aspx#26546 However, there are not a lot of specifics conveyed, although the problem is the same as mine.

  • Beocenter 7700 : Fast Forward is not fast!

    Hi everyone, I have been working on this Beocenter 7700 for the last few weeks and today I finished installing the new idler tires and belts. All new rubber, from BeoParts - 2 belts, 4 idler tires. This amazing video guided me through the process and I followed every step carefully: https://www.youtube.com/watch?v=aBnIB4lDPzk (it's the same cassette mechanism as the 7700). Here's my disappointment: the new rubber tires have made no difference to the Fast Forward. It is still painfully slow

    And, this thread too: https://forum.beoworld.org/forums/t/7325.aspx?PageIndex=3 Unfortunately this may be the issue- old lubricant, which may mean - disassembling, cleaning, and re-lubricating everything. White lithium grease, will it be sufficient?

    Thanks I will. Also, I noticed that the little 4A fuse on the power supply board blew, so that is either the reason it won't turn on, or, a symptom of a bigger problem....

    I removed C96 and it is testing ok- 242uf on a cap rated at 220uF. Not perfect, but still ok I think. Any other suggestions? Is the fuse on the underside the only fuse worth checking? Thanks for your help, David
