Hi All! I've a long term project to restore/repair a Beosound 9000.
Hopefully documenting it on this forum is allowed, useful for others, and may even mean I make fewer mistakes!
I've limited knowledge of the level of electronics/electrical required for this project, but I like to think I'm not stupid (watch me prove that wrong now!)
The main issue, I think, is the power board. I was fortunate enough to receive the 9000 with a capacitor rattling around in the remote control compartment... and I'm yet to locate where that goes! Other issues include missing grub screws, a small wire that seems to have no use (maybe a radio antenna...?) and I've no cables yet...
my current progress here (any comments welcome!):

Progress!
The gap has been found (video)
I've two questions:
A request:
Please do let me know your thoughts, good and bad! I'm sure there is some good I can do by sharing this journey.
(check out the album updates if you've got a Mark II project as well)
my plan of attack is to solder this in with as little connecting wire as possible, and insulating as much as possible!
22uF 6.3v polar capacitor
Having replaced the capacitor, there's little change to the function. As soon as any serious current is drawn the unit shuts down or the backup power system takes over and seems to restart the unit... I'll have a closer look at the motor control and power boards again before looking elsewhere.
Not sure I've noted on here, but it does play radio for a second or so before shutting off. this may help indicate where the issue lies.
