Wings: Your: the problem is that the repair shops dont have technicians able to do these repairs. I, as a hobbyist, can use hours to replicate a part that 30 years ago cost 50 cents, and I know how to do it. On the electronic side a person like Martin can find solutions, but only because he has the know how and the experience needed. Together Martin and I have 80 years experience π.
Your approach to your problem is IMO wrong. Somewhere in Hong Kong there are someone who can repair your item, its just a question of finding him. Getting mad at the people and B&O is not a solution, instead ask them if they know someone who can help you, or if they know someone who may know someone. The way I know Hong Kong, anything and everything is possible.
Of course you can find other new products, even better ones, but it will still, NOT be B&O
Well said that man! I could not agree more.
I told the OP how to repair his Beogram many moons ago, but he did not want to pay, or thought my suggestion was too much grief or similar.
B&O or their service agents will not repair ancient audio/video items, as they no longer have the spares and/or the personnel capable of fitting them. The OP is in the age of the hobbyist/professional repairer and should get used to the idea.
Somewhere in Hong Kong or an adjacent large country is a guy, like me, beavering away doing the very jobs that B&O won't or can't do. It is a matter of finding him.
