I live in north Italy near Switzerland, I tried to take it for service but they don't fix it because they say the damage is too much.

You need to take it to a repairer who is happy to diagnose the exact fault(s) and then source replacement parts from the second hand market. Parts like this are available quite cheaply:

  Guy the problem here in Italy is finding the competent people. The mentality is to cross and not repair. That's why I asked for help. I am not capable and I don't know anyone who can solve it. I got it in a B&O center near Milan... And I took it up again uncovered with irreparable writing. I was also looking for the same used Beocenter 9000... Because in addition to the speakers, I have the Beogram 9000. I wish I could listen to the tha sound of the late 80's again!

by clicking on the ebay link: " MAY NOT POST TO ITALY. READ ITEM DESCRIPTION OR CONTACT SELLER FOR POSTAGE OPTION...."

As mentioned above, parts are usually no problem. What is needed here is a good repairshop or a skilled DIY/hobby-repairer. There must be some in northern Italy. Martin
