Hello, I bought a pair of  beolabs 8000, one of them is working fine, but the other one is not. Opened it up, checked the fuses on the transformer PCB and they were blown. Replaced fuses, plugged in, and no sound. The light goes from red to green to red again as it should, but no sound. Opened the speaker again, checked the fuses and noticed they were blown again. Anybody have any ideea idea why this might happen? Thank you.
