Hi, I have checked the speakers and they will need replacing due to rot. I'm in the United Kingdom

Hi Im new here so go gentle! My dad has been working at someones house and they have been throwing stuff out. He aquired a beocord 6000,beogram 6002 ,beomaster 6000 and 2 x beovox speakers cx 50. I appreciate these items are quality , i can see that. We have kind of tested them but not really knowing how they work find it difficult. All equpment lights
