Hi everyone
I have a Beolab 8000 in working condition , but has a background noise (brumm) all the time .
the internal connection from the audio plug to the amplifier I have disconnected both side , the background sound remains stedy on. because of this sound the loudspeacker is not going to the standby mode.
the dissolfing foam I have removed and the prints are cleaned from the remaining trash.
Does anybody has an idea how to proceed?
Thanks for answers.
regards Ueli
