Hello everybody

Last week our BS4500 started having some problems. First the phono sound started to mix with radio sound (phono in the right, radio in the left speaker). Some days later, the sound of all sources was disturbed by intermediate "klick" sounds, which started about half an hour after the bm4500 was switched on.

As we ordered new active speakers (BL2, 2xBL3), we put in our spare BS7000. For optical reasons, we would like to switch back to BS4500. Any idea how to repair the bm4500 would be appreciated very much. I did a lot of changes of capacitors in BS7000 and BS6500 but here i even don't know where to start. The system consists of a main room with BM4500 Version 2.1, BG4500, BC4500 and BG4500CD. All parts have black cases from BS3500 and covers from BS4500. There are three other rooms connected (two with MCL2AV and T-Amp Amplifiers, one with MCL2A).

Thanks in advance for help

Best regards
