Thats just amazing Søren, how much, and send to my sister in Horsens😁
On the pic I saw before I bought it, I could see the aluminum piece with Treble written on it, so it would be easy to make a new plexi part and glue it, but the text piece must have gotten lost by packing or unpacking. It came in a big flat screen box, very good packed, but to get it into the car trunk, my son had to take it out of the box, and maybe it got lost there.
I will PM you the address, please tell me the price and shipping cost.

Here are the pictures of it
Started the restore, first thing is the serial number, if you dont post this someone will ask for it
Then bottom and top cover of, here the bottom cover, very dirty, and looks like someone tried to spray some cleaner or such into it, to no avail.
Bottom and top of, here inside bottom view, looks OK. No signs of repairs.
Top inside, dirty dirty dirty, and someone did something to the output transistors, seeing this I decided not to plug it in for test, before its clean and the ugly red caps has been changed
Went to the front and checked all the switches, all working but with delay or slow, but a good cleaning and lub will help
Started taking the thing apart, missing a screw here and there, some screws loose, someone was in here before me.
Got a look on the sliding poties, never seen anything that dirty, in any of my BMs
Got it apart, and now onto the cleaning and change of caps, will check the presets as well.
Will be a big job getting all that in again
More to come tomorrow or in the weekend.

Wow Søren! I'm glad I didn't have to dismantle mine completely!
I did that on my Beocenter 3500, phew, what a job it was... but entirely worth it of course 🙂
I wish you the best of luck, and don't hesitate asking!
Pity about Jeff by the way... 🙁 Maybe this thread will cheer him up and give him the guts to fix his. Personally, I'd sue.
Wonderful thread as usual from you. 🤒
I'd wish, I could find the drive to do some resto threads again myself.
But oh boy, that frontpanel can take hours to fit and align.
Was it absolutely necessary to dismount it, what was the problem ?
The "wet" area on the bottom plate is around the signal level trimmers. It's very common to find these
soaked in contact cleaner (or sometimes even the dreadful WD40 or some other nasty stuff) from an
owner or repairshop, desperate to get a little more life out of the oxidized trimmers.

Oh yes, don't do it with children around! Get a few hours' rest before doing it...
Do you think you could post higher res pictures Søren?
